If this is the case. What if a child was not aborted, was born, grew up to become a Hitler, or a Charles Manson and ended up going to hell. Would you not be doing such a soul, a favor to abort it? As maybe these people became what they ended up becoming, because of a terrible life in a unloving household, and would never have been this way and would have received a heavenly reward, had they never been born.
You wouldn't know that this is what they would become though would you? So how could you make the call on such a decision? I reckon you'd love the radio presenter, James Whale (?sp), he holds the view that boys should be sterilised at a very early age and only get the op reversed once they have been certified as capable of being good, responsible parents!!
I question your seeming generalisation that bad people only come from unloving households too - bad people can come from anywhere. Likewise, good, successful people can come from the most unloving households, some of us here are good examples of this
On the religious aspect, what if Hitler or whoever repented in a split second just before he died and he's now in Heaven?
Another, not entirely unconnected thought I've been toying with over the last few days is what if Hitler was doing God's will - would God still send him to Hell? How can He punish someone for doing His will?
No answer to your question - just putting some fuel on the fire!!
