I'm currently replaying Deus Ex: Human Revolution. Everybody likes me, I help everyone, I'm honest and sincere. And I kill all my enemies with headshots and/or criple them with complex bone fractures. I steal everything I deem valuable. I'm not even halfway through the game and I have killed over a hundred people.
Yep, I'm the good guy. Because the ends justify the means.

I remember playing Fallout 1/2 and being a "Savior of the Wasteland" and being a stealthy character robbing everyone blind. I'd pickpocket fancy armor off some shopkeeper and then promptly sell it back to him. I did however give most slavers the dynamite in the pants treatment on general principal.

Fallout 1 & 2 were the motherfucking shit. The original Deus Ex paled in comparison and Human Revolution was no where as awesome as the original, both very good (the original being much more ground-breaking obviously) but no where as awesome as the original Fallouts or Baldur's Gate or Planescape: Torment. The Black Isle writers were impeccable. It's sad that we do not have counter-cultural pop artists in the game industry making ground-breaking games anymore, and for Deus Ex games - we no longer have Looking Glass Studios type shit since they no longer exist and the company that took inspiration from them - the Marin Bioshock team decided to go a direction that was less "survival horror" with Bioshock: Infinite. But, that said, I will gladly play Fallout 4 and I will love every second of it regardless.

Love all the Fallouts, though I never played Tactics. Can't wait for 4!

People are free to invent their own morality and live however they choose, but it doesn't mean there isn't a right way to live.

I understand your point, but you should have used a different game as an example. HR lets you choose how to play the game using lethal or non lethal means. It's entirely up to the player to make that choice.
