Here's a Christian revered in his homeland

Vlad Tepes, aka Vlad the Impaler.

And despite what people claim, that is not who Dracula is. Inspired maybe, but definitely not him. That was some horseshit a bunch of pseudo-scholarly types claimed back in the 70s. There was this fad for treating fictional characters like they were real and analyzing them as such, what made them tick, their historical basis. The only worthy result that came out of that crap was the book Wide Sargasso Sea. The stupidest shit that came out of that was the connecting of Dracula to Vlad.  It was bullshit then, and its bullshit now.

He was in fact a knight from a Christian military order. And kicked a lot of Muslim ass, often having said Muslims have large giant spikes up their asses and left aloft for gravity to do its thing. Sure, he had a kind of violently psychotic dislike of his enemies, but he was fighting invaders, heathen invaders to his eyes. He was totally justified in slaughtering those savages. Unfortunately, he wound up very dead and in several pieces, so he kinda failed at the job at hand.

He was a hero to his people but he did atrocious things. I'm not excusing him but let's not forget the horrible things the Turks did to him when he was imprisoned there, and to his people.
