I don't think you need to be defending his actions to say he didn't deserve to die or to still feel sorry for him and/or his family.
Me personally I never liked him at all despite him getting pretty big hype in the rap community, and he does sound pretty scummy but I'm not gonna sit here and say he deserved to die or that I'm happy / don't care that a 20 year old lost his life in a murder, that's heartless too. It could be karma but it doesn't mean his death should be viewed as some kind of comeuppance.
