Runaway and a confrontation has died. Stay,and you may. When your back is up against the wall, protect the wall as if it is your brother. Remember, it is guarding your back when no one else will. Bravery is a perspective for observers and winners, rarely consoling the losers.
Confrontation deceives the insecure attitude into reacting from fear.
If you are not willing to kill, do not fight a killer. Even when sparring, establish a line you will not let your opponent go past. Guard it with everything you have, or train yourself to lose when it is all you have between life and death. Do not be goaded into half-heartedly fighting. Either fight with your whole heart or leave with both sides intact.
