mostly mannerism, though the line is drawn pretty wide and vague. if you KNOW you're gonna lose a fight and you escape, I wouldn't blame you. that's a tactical retreat. it's a pussy move, yes, but it ensures another day of survival. what I meant by wimpy is a guy who wouldn't stand up for himself at all. I'm not talking about some quiet fighter holding back, I'm talking about some weak coward whose personality is in an oros borous with his actions. he willingly gets himself fucked up and that in turns fuels his further draining personality, type shit. i get that in some cases, it serves to reinforce certain themes in a story but don't expect that character to earn big points with me from the beginning.
in this particular scenario, if there were two equally scrawny kids facing this guy and one of them decides to bail while the other stays behind to fight to the death, I wouldn't fault either two. rationality and bravery are good traits to have. but if both of them were to die and I could only buy flowers for one, I'll be dropping them onto the grave of the latter scrawny kid.
just saying.
