You were the peacemaker Doody, I know sometimes you were moody
But you hated confrontation and truly hated the feuding

from Eminem (Ft. Obie Trice) – Difficult Lyrics on Rap Genius

Meaning

Proof was a peacemaker rather than a guy who looks for trouble. Maybe sometimes he would get mad, but that wasn’t his true personality.
He actually squashed the ICP / Eminem beef a year before his death.
