Where arth thou Wrath?

So in the story of the flood the reason for the end of every thing in existence with the exception of a safari life boat with a six hundred year old captain, was simply a world full of violence. A punishment on that level you'd think would give the people of the old testament some pause before they even squashed a spider right? wrong Genesis thirty four is just as violent and upsetting as David Plotz described it to be. so when I turned the page to Genesis thirty five I was getting ready for a divine smack down of epic proportions, only to discover i was to be disappointed again. Even after the terrific show of exceptional violence by Jacobs son's in thirty four nothing happened.All that happens is Jacob and his sons take a hike up a mountain build an alter and all is forgiven, God even graces Jacob with a his presence and gives him a bomb new name. this passage left me very confused and I gotta admit kinda concerned, because before I had known that God in the old testament was very harsh in his punishments but until this passage I had thought him at least consistent in his furry, but clearly this is not true. so who knows what will set him off again.
