He's not equating Asif's actions with Hitler's; in fact he specifically said it was impossible to compare such things. There's no doubt that Hitler's evil was far greater than Asif's, but when looking at the men rather than the outcomes it's not really quite as simple.
Hitler's evil was a result of a "perfect" combination of good and bad qualities. Without the good qualities he possessed, his bad qualities would not have been enabled and his evil would not have been anywhere near as great or as damaging. Imagine a Hitler with all the hatred, blood lust, lack of compassion and general inhumane outlook of the world that the real Hitler had but without the conviction of character, drive to succeed, charisma, leadership skills and determination that he had. This Hitler's impact on the world would've been extremely minimal (not of his own choosing, of course) and his evil far less pronounced, but he wouldn't have been a better man by any stretch of the imagination.
It's possible to admire Hitler for what he managed to achieve while still condemning his goals, his ideology and the unspeakable evil he committed on the entire world. Scaly's point was that it's impossible to really compare Asif with Hitler because one's criticisms of them are so different. Asif, as well as being a ****, is a degenerate with no admirable qualities (other than bowling, perhaps
) and while Hitler committed unspeakable acts that Asif will never approach, the difference in the men perhaps lies more in what they were able to achieve than what they'd be willing to.
