I really despise, "Everything happens for a reason, things don't happen without a purpose, God's plan.." and anything of that ilk.
Rape, abuse, poverty, disease, war, loneliness, neglect, torture, natural disasters, and every other spontaneous and senseless act of cruelty that happens in this world do not occur on account of underlying divine purpose.
These horrors are often random, irrational, unpredictable, and beyond our comprehension. There is nothing to be gained from going through sexual abuse, being traumatized is not a learning experience that makes the victim stronger or more enlightened, it only destroys you from the inside out.
Trying to ascribe lesson learning as a reasoning for why these terrible things happen is nothing more than an attempt to cope with the existence of unpreventable and unspeakable tragedies that didn't NEED to happen.
Also, I'd like to think that a compassionate creator would not subject his progeny to such sisyphean acts of torture.
