Why do Humans have to Break so Easily?

I've always found it sad that Megaman's going to live so much longer then Dr. Light and spend most of his life (assuming he survives) without him even though he's mentally still going to be a 10 year old boy and is completely unprepared for that kind of responsibility.
He probably wouldn't understand the concept of human death either. </3

Just some background practice, don't take it too seriously :3 My tablet broke while I was doing this so that's why the shading/lines suck so much. It's also why I didn't put words on the tombstone.
