Perhaps this post has attracted so many responses is because there are so many people who know what you're up to (c'mon - don't be coy).
You asked the most bizarre question of the year thus: "If They Are Found To Be True, How Can Some Commit Such Acts?".
The answer is bleeding obvious (if the allegations are true).
It's because they're flipping child molesting, raping scumbags.
It's such a silly question. It's like asking, "If the allegations against Fred and Rosemary West are true, how could they have killed their own daughter?"
Because they're evil, that's why.
Oh, and the reason you posted this question is simply so you could refer to the case, because you find it interesting and it supports a point of view you wish to express. There's no harm in that...I do the same in stories I'm interested in. It would just be refreshing if you were a little more...open about it.
