i am almost baffled by the situation

An argument from emotion is no valid justification.

this is your moral or your maxim, i could get it but i would ask you.
you dont entertain your emotions.you never called your loves one " my son" or " my dear "

I think you misunderstand. When justifying what is moral, not taking into account your emotional standpoint does not mean that you don't have emotions. It means you're making a decision from a non-subjective standpoint that would be applicable to everyone despite certain individuals disposition toward an idea.

but i want to know what is moral code for an atheist. so far it has been said that if an act which does not harm others should not be condemned on the on the account of some emotional tilt.
now i ask can i eat the meat of my dead ones ? no harm for other is involved here.
