Does God have emotions ?

Very much so, only He is not consumed by or controlled by emotion like human beings are.

If "god" lashed out at people in the bible, it was through anger; and as anger (wrath) is one of the deadly sins, he (if it exists/existed) is a sinner, so is in no position to judge "mere mortals". On the other hand, if it made us in its own image, how and why would it get so angry? It looks more like it needs to sort itself out....that is, if it does exist, or ever existed....
