Tell me, how do you know the 六十多岁的老头 was not 叛逆 when he was young? Do you have any evidence indicating the people who have not gone through 叛逆 are more likely to committ crime? Do you know the US is the champion to have series killers in the world?
A mature person should respect the facts. One should not twist the fact to "prove" his/her thoughts. At least try to use facts to support your conclusion.
