If anyone understands any Latin languages, in the ending he apologizes to whom he might have offended. Not that that makes it right. But it isn't as offending.
Let's just say, god forbid, you died and someone made a video of your death using a video game and then at the end, who ever made it, said that they apologized to whom they may have offended. Wouldn't you be as equally offended if they didn't say that? I mean you would be dead, but I think if you saw it you would be pissed.
Personally I don't find this video that offending because if Hollywood could make movies about 9/11...then why can't anyone else? I'm just pointing out that just because you apologize for your actions, that doesn't make what you did right.
