agreed.
Sometimes we should look out for our own. We don't need to be a specific profession in order to attempt certain things for people.
It's kind of like Soldiers who have basic medic training (which almost all Soldiers have, though not all try to get Combat Medic certified) rushing in to help a swamped paramedic.
When it comes to individual combat, not everyone is certified, but everyone probably has some ideas.
Just like the fact that all Soldiers aren't confident in their ability to administer aid, not all humans are confident in their ability to perform in a brawl. The ones without confidence should obviously stay back, as they may just cause more damage. Hell, many who are confident may still make the situation worse.
But dammit, some of us should at least try. So you may lose your own gamble and perish in the attempt.... we should be able to help each other out like that. Some people take daily life way to seriously and have a strange desire to see old age. I'll take whatever years I'm able to get, but I'm not going to go out of my way to avoid risk if someone else deserves an attempt to render aid. We're humans, and we should provide aid for our own. And hell, criminals killing others just to kill are disgusting examples of humanity, and the shot to take one of them out is equally as rewarding as the potential to save someone. Get to hit two birds with one stone: help a friendly, destroy an enemy.
