The game isn't all about black and white, it's all shades of grey.
Now game essentially tells me: "Hey, you tried to do essentially right thing (to punish a cold-blooded murderer), so everybody hates you because you don't tell anybody what are you doing and why. Ah you
wanted do but there was not such an opportunity? Haha, pwned you, it's cruel world, we don't always takes anything we want."
It's not "shades of gray". It's writer' laziness.
Such things can be met everywhere, of course - when quite obvious and sensible approach to situation in game is blocked by "no such option", because writer and game designers together couldn't find a way to MAKE me choose between two bad options in a situation where such choice is obviously avoidable. So they just don't me an option to do sensible thing because just that. I believe it's not-so-good-job, but ok, let it pass (quite obvious such solutions, though, won't make me to think and really empathize to situation, because it's obviously mechanical situation trying to make me sad on the plain spot). But please, dear developers, have a pin of decency and don't mock
me for
your bad work.
