I wasn't in his life for th' longest time but, I found my folks and found out I had a brother an' did what I could t'help him. Even after he betrayed my trust I still helped him out.
But there's a certain point where y'can't keep reachin' a hand out only t'get bit. They gotta wise up on their own an' realize what they're doin' t'themselves or what they're potentially throwin' away.
I'm not sure how that could work in war time, guess if your buddy keeps runnin' in there ain't no sense followin' only for him t'git ya both killed. Especially if he won't listen t'nobody.
