Monson is an incredibly nice guy. A gentle soul. Regardless of his far past.
Doesnt surprise me at all. Since he was the damn leader of that crew he was in he would probably never need to use any violence. Everybody includning the blind, death and mute would know that he should always be shown respect. When you have the power to kill other people in a blink but still acts calm, polite and respectfull to others he proves right there that hes a very good man.
