I've said this before, but it bears repeating.
Sleep is for the weak.
I never said I wanted to be strong, dammit.
I'm sure I've seen it more than once in anime, some badly written villain claims that "weakness itself is a crime" the strong rule, blah blah. The villain is made intentionally unsympathetic.
It doesn't apply as much in real life as it does to role playing.. I tend to limit my characters' strength. All of them are more useful outside of combat than on the field of battle. There are a few reasons to this..
A form of self-defense.. One who is no threat doesn't need to be killed. Living at the mercy of others.
Of course that never works, because the villain is evil. He'll kill you if he can.
So it's suddenly your duty to become strong, so you can stay alive. Because people depend on you.
But with power comes responsibility. Shirking this responsibility by intentionally staying weak is cowardice: this is the crime of being weak those villains spoke of.
I think too much about the idea of strength being a form of weakness, and vice versa.
I think I think too much, period, and that is why I can't fall asleep.
