all the people in naruto run that way and idates past is comparable to hakus on the same level that zaku's is. in fact less so because it hasnt been revealed if jirochu(sp?) is even a ninja yet. he may not be the one who trained idate, also haku never hated ninjas, and also nothign abotu the fate of idates family has been revealed only his brother who is in fact still alive. so id say they were quite diffrent TBH
