I think Telltale gave a brilliant example on why violence isn't always the answer.
In episode 4 of the Wolf Among us, when you had the option to hear him out...
"I don't know much about those whores.."
That would probably piss you off, it did me too. After the third play through I decided to hear him out.
"If they're dead, it's because the Crooked Man wanted them dead. That's all it takes."
Unbelievable. All I needed to have no Mercy on Crooked Man.
What were other examples that telltale used to show us that violence isn't the answer!
