I remember a rowdy classmate in primary school who was physically punished by the teacher. It got so bad that the parents came. The parents wanted to whack the kid. I was sitting nearby and I cheerfully offered by stainless steel 30cm ruler to the mother when she requested for a 'weapon'. That kid's cries of pain were sweet melody to my ears.
And no, I wasn't bullied or anything. I was just a smart kid who aced my exams, enjoyed my PE lessons and my sessions with the school dentist. I just loved seeing other people suffer, for no reason at all. I was 变态 like that.
You possess the qualities to be a good PM or President because they are all 变态 !
