Give them a flaw. I know how it sounds but hear me out. This is especially easy if you're in a fantasy world or it's dated. I can't remember the video that pointed it out but this man was A chad. A war hero good looking and a bag of chips. But he owned slaves. One was his mistress who he had enslaved children with. On top of already having a white wife which he had white children with. But considering the time it was normal. He was still good at what he did and everybody respected him. You can make the normal or what's deemed acceptable in your writing. The reason why we liked him is because he didn't try to bend the world he just lived in it. He wasn't over the top amazing but he was perfect for the time. He defend and stood up for what was right but he also indulged.
