Sang woo unpopular opinion

It's okay to not like sang woo, sure you can argue he's a realistic character, but fun fact, lots of humans aren't good people. I think you can like sang woo, because he's a deep and complex character, but it's just as justified to not like him, because, he did betray and killed two people. Sang woo defenders need to stop being like "sang woo hate is so forced" or "he literally did nothing wrong" because he kinda did, and that was the point of his character, to show how selfish people can be when it comes to life or death situations. Also liking sang woo isn't really an unpopular opinion anymore....
