Many freewill theists oppose divine impassibility. Although Rauser is a liberal Arminian, he has his broken clock moment in this post:
Reminds me of the widely reported story about a scorned girlfriend who retaliated by drugging her ex-boyfriend and then extracting all his teeth. Now, that story may have been a hoax, but one reason it went viral is that it was plausible. Betrayal begets revenge, and revenge knows no bounds.
Many short-sighted Christians like the idea of an emotional God whose psychological makeup is very human. There's a whole "suffering God" literature.
They haven't given much thought to what it what omnipotent revenge would look like.
