On necrophilia - I don't know what that is but will say of it and all other issues read romans 14 verse 1 - 23 especially read verse 23.

Necrophilia is having sex with dead people. [Probably not the first thing that came to Paul's mind when he wrote those verses in Romans...]

Also if our pedophilia is not from God than why doesn't he remove it since he will not let us be tempted beyond what we can bear and will make a way of escape.

The problem with that argument is assuming you CAN'T bear it. Yes, it's difficult, but others have coped, and you can, too (in His strength).

I don't really have anything else to add, other than to wholeheartedly agree with Dakota in his post here:
