It is your doom to be so.
Consider this. Had Robert Byrd died in the early 1960s, he would have been considered an evil man, an unrepentant Klansman.
Had Hillary passed away in 2000, she would have been a homophobe for opposing same-sex marriages.
Don't even get me started on Robert E. Lee. No matter what he did that was good and noble, he was definitely evil because he fought for the Confederacy. Had he lived another 150 years, he may well have been able to redeem himself like Robert Byrd, but he did not and now he's on the Wrong Side of History.
You will be, too. That's the beauty of modern ethics. What was innocent before is evil today. Since these ethics are continually shifting, it's preposterous to think that there is not going to be some future time wherein something you're doing today will be considered the epitome of evil, outweighing everything else you have done.
Try that on your kids' teachers next time they teach lessons about the horrors of Western civilization. "Oh yeah, Ms. Garfinkel? Well you're evil and I refuse to allow little Edgar here to be taught by an evil person!"
That should provide hours of entertainment.
