A philosophical expression: (Nothing I type below should be construed as supporting proactive violence against any person, group, or entity)

When one understands that death is a surety, that none of us get out of here alive, it can be a comforting thing.

We are already dead. The only reason those who understand this fear death is because we don't want to leave our loved ones without our aid, we don't want to have our chance to fight back, to make the enemy pay taken from us.
