WackyDan:  You are correct to a degree... 
M:  Maybe you noticed that when I posted I used terms like 'it seems to me'.  I think what you meant to say was that I am correct to a degree in your opinion.  I personally believe I was a lot more correct than you think, as I will show:
WD:  But the variable is always going to be the individual and freedom of choice.
M:  I suggested that I do not know what makes one person who experiences misery empathetic and another cruel, but I suggested it might be environmental factors like somebody in a child's life who shows them self respect.  What you seem to be saying is that it is deterministic somehow, genetics, the will of God, karma for bad behavior in a previous life, or God knows what.  In other words you aren't saying anything but that A is one way and B another, end of story.  And I also do not believe in choice.  As long as people are motivated by unconscious forces, and I see nothing but evidence for this, they are motivated by unconscious forces.  You do not act out of choice when what moves you are things you cannot see.  I would assert, for example, that your belief in choice is motivated by a need you do not know you have to think that way.
WD:  You can help some people, you can provide a support structure and influence 2nd to none and yet they can still end up being a gang member, homeless, a criminal, a drug abuser... 
M:  There may be people who are born with brain abnormalities that make it impossible for them to experience empathy.  They are not actually born human.  These cases I think are rare.  Otherwise, we can have no idea whether what you say is true or not because we do not live in a world where children are never put down.  Everybody gets fucked over as I see it.
CW:  There are people that you can never apply logic to... 
M:  There is no one you can't apply love to.
WD:  Given the right environment and "steering" I'm sure we'd end up with less people in misery/squalor... but you will never reach 100% of them... and some people just can't be helped no matter how much you invest in them... in time, money, yourself....
M:  So lets get busy doing what we can now because if there are some that can't be reached it may be because it's now too late.
I believe we tell ourselves stories to protect ourselves from seeing that we are our brothers keepers and we have failed.  It is much easier to say that some can't be helped than never to give up on anyone.
