Putting others down to feel good, is a bad strategy

I had a conversation with a girl and an idiot of a guy, who I'd better off without, he makes fun of everyone to make himself bigger. Actually me and a girl were discussing movies, and we kept talking and everytime I made a comment about a movie, he felt the need to put it down, at the time omg, it was annoying, I wanted to punch the guy in the face really. Now I feel sorry for that guy, it's like a drug. Instead of looking what to improve about yourself, he has chosen to make up for his inadequacies by putting others down. I learned a lesson today. He is not going to get a good life staying on this course, and I sort at look at him with glee.
Again I need to be aware of my own shortcomings and not pointing fingers at him. I wanted to share my frustration Thank you

 

Thank you, I like you pointing out he is insecure
