This is a golden oldie, I did this picture for an assignment
in my high school English class in 9th grade. I forget exactly
what the assignment was, but it was something relating to Paradise Lost which
we were reading at the time. The angel has been sent to strike
down the demon, but he takes no pleasure in it. This angel feels
sorry for the demon he's striking down, since demons were once angels after
all, but he doesn't have a choice.
I'm actually in the process of redoing this picture, check
it out here!
