Why do you harbour hate ?

You came naked, You will go naked. You arrived weak, You will leave weak. You came without money and things, You will leave even without money and things. Your first bath? Someone washed you, Your last bath? Someone will wash you. This is life!!! So why so much malice, so much envy, so much hate, so much resentment, so much selfishness and so much pride?why, when we have to go empty handed?
