As a founder, I have three levels of responsibility. A responsibility for every individual I hire, which I respect to the maximum I can. On top, a responsibility for the team into which I hire an individual. On top, a responsibility for the company which I am building.

I've lost teams. I will fire any individual who will endanger a team by sabotaging it or not carrying the same weight as the others.

I've lost a company. I fill fire any team who will endanger my current org.
