-"So the best strategy here would be to flank the main body with two sentries and have one special class on backup…"
The lecture about battle strategies was going on and Sam was nothing but bored.
First, he had memorized more advanced battle strategies than what the teacher was teaching right now before he even turned 10.
Second, most of these strategies were meant to apprehend the opponent(s) and not kill them.
Why? Because Heroes rarely kill. Unless it's not a high-ranking criminal or a Supervillain, Heroes refrain from killing.
Although it's not wrong morals for Heroes to have, Sam couldn't help but find the "no killing" rule bullshit.
If you really want to vanquish all evil from the world then just eradicate all evil doers.
He knew his thinking was broken but he has accepted his broken point of view a long time ago.
