I've never heard that explained like this, cheers. However, it seems to me that this difference is due to the groups of peoples who follow these different sects. For example, teenagers are hot headed, but perfectly happy to go off and do some questionable stuff, then cross themselves and ask for forgiveness, to finally go off on their merry way and have a tranquil adult life. Whereas we adults are less forgiving and tend to care less about others, and cannot easiily forget when somebody has betrayed us.
