if we look at Avatamsaka Sutra, Sudhana's visit to 53 gurus. 19th stage bodhisattva 胜热婆罗门 displayed a foolish ignorance 'guru'. 27th stage bodhisattva 甘露火王 displayed a hateful, mean, wicked, evil king, who was a 'killing machine'. 35th stage bodhisattva 伐苏蜜多女 displayed an indulgent lustful prostitute. All in all the 3 posions. All these high level bodhisattva are able to 'display' as false evil doers(even meat-eaters) just to 'show' sentient beings to learn from their mistakes and that it's unwholesome, 'don't follow me' per se.
of the many different methods of delivering beings, there's one form that uses mean and wickedness. when 甘露火王 (Gan Lu Huo Wang) delivering evil beings. evil beings think they are evil, but when compared to 甘露火王 (Gan Lu Huo Wang), they would have to kowtow and quietly listen to the "King", who would eventually lead them to Dharma.
而法身菩萨是善恶都随缘。《华严经》的“善财童子五十三参”，胜热婆罗门示现愚痴，善财童子参访他，与他同事。伐苏蜜多女示现贪欲，甘露火王示现瞋恚，杀人不眨眼，但他们在境界里得真清净，一念不生。若非法身菩萨，决不能与之同事，若与这些人同事，没有不下地狱的。胜热婆罗门、伐苏蜜多女、甘露火王做这些事是成无上道，不会堕地狱，他们是在境界里修清净心。所以，到那个境界，“淫怒痴”即是“戒定慧”，是一不是二。我们不是法身菩萨，“淫怒痴”就是三恶道，“戒定慧”是四圣法界，这两个境界迥然不同，因果不一样。法身菩萨契入一真法界，妄想、分别、执着全断了，所以“淫怒痴”跟“戒定慧”是一不是二。我们有“我、你、他”，有分别、执着，随顺“淫怒痴”，决定堕三途。这必须要清楚、明了。-MCKhttp://sg.wrs.yahoo.com/_ylt=An4yiYaFnK ...

Even though 甘露火王 (Gan Lu Huo Wang) displayed a hateful, mean, wicked, evil king, who was a 'killing machine', he's mind was dwelling in pureness. Unless One is a Dharmakaya Bodhisattva(11th stage and above), one cannot have put this off. Ordinary beings commit these would only lead to the hell realms. At their level of cultivation, greed, hatred and folly are but discipline, samathi and prajna to them. They are one not two. okay, but we are not them.
