Adolf Hitler was surely anti-christian warrior, but "Antichrist" is a title of Fifth Son of Satan and First Human -Adapa, given to Him by enemy, as same as "Beast" in jewish bible. Antichrist means the same as alter-christ, because this "christ" is alternative jewish version of this Son of Satan...

This is curse and nothing else. But even not with using some spiritual powers (growth/knowledge based), but only using emotions and some simple props to make it. -Mainly using by christian criminals as "reinforcement", of their physical action against someone.

"Heresis" is Greece word, which means "freedom of choice". It explains who always been the most enemy of catholic church.. Satan wants only heretics which know why they want to follow Him.
