I did not find that Master Samael Aun Weor had actually said that. Instead he had said the following:
"Whosoever wants to be liberated from the fatal Wheel of Samsara must dissolve the “I” and incarnate the Soul. This labor is very difficult and those who achieve it are very rare." http://gnosticteachings.org/glossary/m.html
This, to me makes better sense, as coming from someone known as 'Master'. He does not say to directly "Kill the 'I'", but suggests that the annihilation can be accomplished indirectly.
Understanding its many ways – how it functions - through self-examination is the method. Thus it will dissolve away on its own accord through the method of self-observation. Ego is made for conflict, to fight, to survive – fighting with ego is playing the game of conflict that ego has very much championed several times over.
Surely, ego is needed for survival. But when survival has been achieved, when affluence has be achieved and one can comfortably survive, is it necessary to continue carrying an attitude of conflict, competition for survival with you?
A boat serves a purpose to traverse a river, but after crossing the river, is it necessary to carry the boat on your back over mountains, into valleys and across deserts? The hard casing shell of the seed is needed to help protect the seed from a harsh environment, to help so that when the seed finds the right soil, it can begin to grow, to sprout into becoming a tree, or whatever. But if the seed has found the right soil, and is ready to move into growth process, but clings to the shell – the shell then becomes a hindrance, a barrier, to its own growth.
Clinging to the ego, because of what it has done in the past during one phase of one’s life, becomes a burden when attempting to move beyond the animal stage of one’s existence.
