I like creating characters regardless. Like, it's just that simple. I enjoy the character creation process. It's fun for me thinking how I can add my own spin to a stereotypical trope of certain "types" of characters and/or ethnicities I may go with. And as much as I enjoy making new ones, I also enjoy reusing and developing already-made characters. I don't see anything wrong with that. I mean, if you're just reusing the character because you're lazy and you don't want to make a new one, then I can understand the argument against reusing characters. I, for one, am on the side that likes to reuse characters to develop them. I can explore unexplored paths that I hadn't been able to the first time around. Using the same character multiple times allows you to get to know the character more and figure out things about them you didn't know before.
