@OP: Is that an epiphany I see on the thread title? "Getting away with murder"? Oh puh-liz, gimme a break. Paul didn't even lay a hand on Chimchar, unlike Damian who physically abused Charmander (Damian got blasted off anyway like he deserved), but you're treating him like he's an prison escapee or something.
Just be glad that Paul learned his lesson by the end of Ash vs. Paul rivalry arc, though the majority of the fanbase was expecting it anyway. If it was not because of the plot device, and if Ash got his arse handed over to him by Paul in the league battle, that would have made more sense and would have been more realistic, since Paul was always the better trainer than Ash. Chimchar didn't deserve to be in Paul's team. The careless, aimless spot in Ash's team suits it more. Just imagine how many more matches Paul would have lost to Ash had he still carried the burden of that monkey!
