You don't forget an old saying in China, which says: Yan people are easy to provoke, but kids are difficult ~ ~ We can't simply measure who is more cruel by which one causes more casualties. But compare the way they do things! In this respect, bin Laden is obviously not as famous as Barcelona ~ ~ But bin Laden is a decision-maker, and there is no need to do everything by himself. Barcelona, on the other hand, is an executioner, so he has to take part in many things in person, and sometimes he even sets an example for his associates with his (cruel) behavior.
In other words, bin Laden is sitting in an office, while Barcelona is fighting at the front. Therefore, at least from the external performance, the latter's behavior is obviously much more ferocious than the former! ~~
