"Some people can't cross the line, they just lock away the criminals, the monsters or scare them away.." They believe if they step over the line for a second, they would never come back. 

Criminals are like weeds

Others try and kill them , and live long enough to become just as twisted, becoming the monsters.  Overwhelming themselves, reacting with the ultra violence.  Becoming strict, broken monsters. 

I fight for the people. The weak. The innocent. Anyone who can't protect themselves. When they cry out for a savior, I'll answer. As for the criminals who threaten them? They need to know that their actions have consequences. 

That's not who I am, I stand between both of them... A balance I'm the light in the darkness with own darkness inside of himself.  I can walk the line, I know I can..
