Keep in mind what Itachi said: you don't really know what kind of person you are until you die. The 2nd was indeed a jerk, but he also quickly realized he was dead, being controlled, and hated both. There was no point in him fighting the living. Yet, once he discovered the ninja were too weak to beat him, he stopped helping and said that if they were so weak they didn't deserve beating him. When Gaara and Onoki were pulling punches on him he clearly respected them for that.

In other words, he was a jerk, but he wasn't a jerk above reason.
