Anyone Else Feel Guilty About Changing a Sim's Genetics?

Oh definitely! I typically never alter sims who have been born in my game, but I had a plan in my head for who would be the next heir in my game before I even reached the generation, and he was born with the wrong hair color. :( I flipped a coin to see if I would allow myself to change it because I was so conflicted lol I did end up changing it, and he just became a young adult a couple days ago
