i would want my favorite character to be flawed lol
perfect characters never exist and i want to see cool anime characters and like to imagine them in real life
Flawed and even the most heroic actions can have minute negative impacts. It's normal and I would never dislike an anime character based on such flaws and when I do like an anime character, it's because they have some of my traits.
Even when I role play characters, I purposely find interesting quirks and flaws to add to my character. Perfection is boring. And nothing is perfect. The same is true for any fictional character, anime or not.
