My call would be Solid Snake from Metal Gear because even though will take down any threats to his safety and freedom, he tries to see things from their perspective and a lot of times he honors the enemies he has killed. He also has knack of saying the right thing at the right time to defuse a situation or encourage someone (eg: Raiden when he wanted to kill himself in Meta Gear Solid 4, it was Solid's words which gave him the will to live on.)
