Frank Castle (Earth-1600)

"In his own way, he knows whatever he does to defeat crime is right, even if everyone else doesn't think so. When he fights, he thinks of how he helps people, without even realizing it, and is very determined to help them, which is pretty much something every other super hero has that sets their lifelong goals. His methods are questionable, but he reminds people what awaits the world, and doesn't wait for that certain thing to get punished."

- Allen
