I LIKED Under the Hood. It made sense that a Jason who had gone through the trauma of being betrayed by his own mother, beaten, blown up and buried only to wake up to a world where Batman had seemingly moved on as though he had never existed, would feel majorly pissed off and betrayed. I confess, I cheered when he brilliantly conned Black Mask into killing his own men and then he kidnapped the Joker and beat seven kinds of shit out of him!!!♥♥♥
However, it didn't make any sense that he would evolve into a complete sociopathic jerkwad. Betrayed as he felt, he still loved Bruce and idolized Dick and I'm assuming still loved Alfred too, although he was never mentioned. Him becoming a Huntress-like anti-hero I get. Taking over Nightwing's identity and beating up his replacement to a pulp I don't get. Becoming a supervillain who shoots kids and murders people who aren't even criminals, I don't get. At least Cassandra was supposed to have been shot up with psychotropic drugs which apparently gave her a complete and irreversible personality transplant.
Also, from all I've seen from A Death in the Family, Jason got killed for trusting his biological mother and not being reckless and disobeying orders. So what's with all the "I got myself killed by being stupid and over-confident" rubbish that dates all the way back to A Rite of Passage, when Jason's ghost speaks to Tim?
