If anybody else wants to try, it's; "Why does God put the genetic structures in place that will eventually cause people to become either homosexual or a violent criminal?"
There are certain questions where I can at least theorize some sort of answer to them, but this is one where I really have no idea. The only theory I can come up with off the top of my head is to note the fact that it's impossible to value something unless you can see the alternative. If God made everyone exactly the same, completely perfect in every way, life would be entirely meaningless. Happiness wouldn't even be understandable, because there's nothing to compare it to in order to realize what a wonderful thing it is.
In essence, by creating imperfections, sadness, and other things in life that are deemed as "bad", God allows us to appreciate the absence of these things. You don't fully appreciate the warmth of a house until you come out of a downpour into it and dry yourself off. You don't fully appreciate the feeling of safety until you become worried and subsequently relieved. It's almost somewhat of a paradox, but you can't be happy unless you're unhappy some of the time. If you're not unhappy some of the time, then happiness is no longer a positive thing, and is instead simply something that you assume will always be there, and soon enough will be something that you don't even care about anymore.
This doesn't really account for the people who are worse off than others, though. If God truly wanted everyone to be happy on Earth, he would give everyone the same level of opportunity to experience happiness as anyone else. Thus, I must come to the conclusion that this isn't the idea behind everything. As for what the idea actually is, I can't really say. Perhaps those who lead a troubled life are rewarded more than anyone else in the afterlife as compensation for the ordeals that they had to suffer through in life. I do believe that God loves everyone and does not intend to simply sit back while someone gets everything and others get nothing. He may not do anything for the people while on Earth, but I reject the idea that these people are abandoned.
I guess we'll all find out soon enough.
PS: Okay, I guess I
do have at least
some idea...
