I enjoy controlling calm, ruthless characters, though most of them were in their thirties to forties. I can't help but enjoy watching dem villains being calm even if the end of their villainy is clear. Nearly none of them had redeeming features though; only a few of them were legitimately reasonable for their actions.

I enjoy having fairly aged characters. Playing as young/teen characters just makes me older than I should feel lol

You can have your antagonist be older if you want.  It would put him a step ahead of the younger ones, and there's no rule about age for antagonists anyway.
