I know I m a good person and he s a bad person.?

Do your actions represent your ethics and moral? Do your actions represent your care and love for someone? Can people judge or decide through observing how somebody is or how they feel?

I see my 20year old friend constantly argue with his dad and doesn t put all his effort in trying to be nice or be helpful around the house so it s obvious he doesn t care for his dad or appreciate him. He tells me he loves him which upsets me because I know he doesn t. He said he s depressed which disgusted me because I see people give him love and support him...I believe he s selfish and only cares about himself. I asked if he was good person and he didnt know. I told him that you would know if your a good person or not. He finally said he is! This upsets me cause I m a good person and I see that he clearly isn t!...can anyone relate or have opinion if I m right?
