It's obviously trust. He just said "I believe in you" and shirks the responsibility without asking anything. "I'm doing it for your good" is really for my own good, but it's also so high-sounding. I never think about whether my way is correct, and naturally I don't understand the harm caused by his behavior. Words are used to communicate, but what is truly convincing is what you actually do - I am too selfish, so I am so willful and arrogant. I am just telling my feelings. It is really... So selfish...
