Bill Gates also gives a huge sum of money to Charity and charitable causes. MacKenzie Scott is another. You can believe the super rich don't pay their fair share and not think "all super-rich are evil."
Most reasonable people dont think binary like that.
I'd also like to point out that it's entirely possible for someone to give large sums to charitable causes, yet still be an evil piece of work. Especially if those large sums don't affect you whatsoever financially.
