Christianity and Judaism attribute a number of characteristics to God. They seem to comprise two mutually exclusive sets of characteristics! It seems impossible that even God could actually have both sets as absolutely as is believed by all Christians and Jews.
Implied with this set of characteristics is that He is Logical and Just. His Universe would not be a logical place or even a "fair" place for His created humans without rigidly consistent logic. Examples of violations of that would be if days were of various numbers of hours in length, or if gravity was sometimes twice as strong, or if water was sometimes deadly poisonous, or if you open your front door and sometimes there is empty space there. Obviously, His Just Nature requires that things such as these cannot be permitted to happen.
The Old Testament tells of a number of times when God became Angry at some individual and then "smote" a whole army in retribution. The implication is that those many individuals (soldiers, usually) were NOT guilty of the fault that resulted in their deaths, indicating that they were essentially innocent.
There's a second level of questions that also arise. Since God Knows everything, past, present, and future, how could He have been "surprised" by failings in so many individuals He entrusted, like Adam, and Abraham, and Aaron and David, and many more? And, since He certainly Knew how each of them would act and react, how could it be that He would have an Angry reaction in His disappointment? And in His interactions with Jonah or Job or many others, since He Knew from the start how everything would turn out, doesn't that seem like we would be really "boring" for Him? There was really then no point in the Job story, as God already Knew how it would all turn out, and it was NOT any challenge between Him and Satan after all! Since He already knows our future and how our civilization will end, that would seem to eliminate any "entertainment value" we might have for Him!
However, from Old Testament evidence, it is hard to see how it could be concluded that God could see future events precisely. As noted above, if He KNEW someone was going to let Him down, how could He then get angry over it happening? And so I accept that God has infinite Wisdom and Knowledge and Ability, but that that does not extend to things which have not yet happened.
As to Anger and Vengeance, I truly cannot see how He could have ever have been surprised or disappointed with any of us, IF He Knows the complete and detailed future. So, even if He is capable of Anger or willing to do Vengeance, I cannot imagine any situation when such needs would arise. Of course, the Old Testament in my Bible clearly tells me of many examples of His Anger and His Vengeance. Maybe I'm just not smart enough to see how all this could be true! But I pretty much choose to downplay (and almost ignore) those Old Testament references to His Emotional reactions, because the God I Respect and Revere and Worship wouldn't have seemingly irrational emotional reactions.
There IS another possible explanation for this, but I do not really like it. Noting that our modern Bibles are TRANSLATIONS of COPIES of COPIES of Scribal Copies of Scribal Copies, at least fifty times over, regarding just the text of the New Testament, AND that around 30,000 partial Manuscripts have been found and compared, and that many thousands of (minor) copying errors have been discovered, we are now pretty sure of the accurate wording of the NEW Testament simply because we have been able to compare all those thousands of Manuscripts of it. Regarding Old Testament exact wording, there is extremely minimal evidence on which to base such confidence! This is mostly due to a Jewish procedure where a Scribe would extremely carefully copy the Bible AND THEN DESTROY THE ORIGINAL! Their reasoning was primarily to make sure that the number of existing copies of the Bible would not grow, where there could ever be controversy regarding which one was correct. When only one copy existed, there was never any other Manuscript to compare it to, and so no possible arguments could ever occur over which one was correct! However, it opens the door to the fact that Scribes are humans and therefore capable of making minor errors! So, in the event that the EXACT wording of the details regarding a truly ancient story where God "became angry" might have then been an embellishment by a Scribe, in emphasizing just how immensely powerful God actually is. See the point? There is no possible way to ever reconstruct the details of what happened that day 3000 or more years ago, when the story says that God got Angry!
In fact, I see these recurring lapses of mankind as CAUSING a DECISION in the Lord! In the same way that some Medieval Kings would dress up in peasant's clothing in order to go out among his people to try to learn why they didn't seem to appreciate the many things he tried to do for them, I see the possibility that the Lord may have therefore CHOSEN to "experience an entire human lifetime for Himself". In order to do that, He would therefore have needed to select a woman (Mary) to first have the Baby Jesus (rather than entering human society by an obvious Miracle and therefore making it obvious Who He Was). The Bible even states that He invoked Kenosis (sort of like amnesia) on Himself so that the Bably and Child Jesus would not be deciding to be doing Miracles to cure friends and neighbors or to be entertaining the other children!
With this perspective, then our very self-centered attitude that Jesus ONLY joined human society FOR OUR BENEFIT may not be correct! He may have had an immensely good motivation FOR HIMSELF regarding LEARNING WHY humans had so often failed Him in the past! In addition, by experiencing a TOTALLY NORMAL CHILDHOOD, the Lord might also have gained insights regarding the lives of human children, where He might then be able to benefit them better in the future.
There are MANY other aspects of Christianity and Judaism which seem to fall into excellent compatibility with this perspective!
Until I learn otherwise, my personal answer to the question in the title of this essay, would be "No, God does not get Angry", even though He does not always know what the future holds for us. However, I realize that 99.999% of Christians and Jews would disagree with me. I'm willing to accept their position if someone can satisfactorily explain the points made earlier.
