It's essentially true. The hard part is what to do next. I choose to follow a life where I stick to my convictions no matter where it leads. Sometimes that can mean breaking the law, or simply doing something outside of societal norms and being ostracized. I strive to be as honest as I can, and enjoy bettering myself.
If you choose to go the mass murdering route, in the grand scheme of things, I can't really see it making much of a difference. But I don't see why you wouldn't want to make the world a better place to be for yourself, and others, while we are here. I mean, we are stuck here, might as well do what we can to not make it suck.
