is there any genuine excuse other than giving up entirely and surrendering? (Isalm=Surrender of self)
Self-denial, self-sacrifice or surrender is one of those highly valued qualities among many religious groups, JWs and Muslims included. To be a martyr is deemed a more spiritually "pure" way of life, bringing the person closer to God. Even Jesus said something to the effect of whomever wanted to be greatest in the kingdom of heaven must become the servant.
It's a kind of sick and twisted paradox: the greater the sacrifice, the greater the reward. For humans, what greater sacrifice is there than one's self?
