Motivation is an important part of characterization. There's nothing duller than an entirely reactionary character who never acts out of their own decisions, only blind loyalty or automatic response to a perceived slight. With that in mind, what was Death's motivation for Darksiders 2 again? Help out War who was accused of wiping out humanity without authorization? Okay. Has War's innocence been confirmed to Death's satisfaction? How does Death know War couldn't possibly just go nutbutters one day?
