if this is goin on about the film, then no, certainly not...
he was simply a entity carrying out his own deeds, he doesn't have a secret identity and he doesn't have a moral code to act against.
he did perform some heroics that wouldn't have been able to occur via anyone else but i would rather describe him as a force of nature...
same goes for ultimate hulk, where there is no right or wrong.
as for the comic book hulk, i think he has gone through regions and times where he has and he hasn't depending on the writer, the type of hulk we are talking about and his general motivations against his 'enemies'
