You believe that ego and humility are linked. That ego cannot be rid off. You believe that a humble being is a doormat ie. someone who is too humble and peaceful that he can be led astray. You think that ego is a necessity and a certain amount healthy.
Here are quotations from Gurbani that criticize your thinking
1. Ego and humility are not linked. If one rises the other dies off. Infact they are actually against each other. As you become humble, ego dies...as you become egoistic, humbleness dies.
2. To rid oneself of the ego is one of life's prime objectives. Gurbani states that
A) to kill the ego results in killing of the mind. Without this how can God be obtained.
B) Ego is against Naam and both cannot abide in the mind.
3. Being humble doesn't result in being a doormat. Gurbani states: Gursikh is humble inside but wise as well. In Japji Sahib it states a Gursikh never dies or gets defrauded.
4. Brahmgiani mahapurkh have no ego. In Asa Ki // there is a question "how does the ego die"...kith sanjam eh jaye
In another shabad of Sri Guru Granth Sahib its written that ego is a disease that is unhealthy.
Ego is never a good thing in Sikh philosophy, even a little bit for prorecreation, bir ras etc.
This has always been a false arguement that the 5 evils can never be eliminated but rather should be controlled and tamed
