Hey Linwood, I think there's a problem in the debate here in that some people equate "love" with "choosing to be in a relationship of some sort", while others don't. I agree that if my wife decided she was into beastiality and self-mutilation (not that she has shown any such desire, but hypothetically of course) and demanded I participate too, or my brother murdered someone, I'd have to say "sorry, can't support that" and end the relationship if necessary, but that doesn't mean I can't still love her or him - it just means I have the terrible burden of letting them go or handing them over to the police or whatever may be necessary.
Perhaps I`m just different but my love is never "given", not to anybody, it never has been.
Also everything is subjective when considering "love" to me.
If my daughter killed another person my love wouldn`t be diminished due to the act of killing.
It would be diminished (or perhaps even increased) depending upon the reasons surrounding her act of killing.
If she killed a man protecting herself or others that might actually increase my love for her.
This is because I love "what" she is, not "who" she is.
If she should commit a killing in a manner that is morally necessary to me that would probably show me that "who" she is is even more admirable than I previously thought as I don`t imagine killing is an easy thing for someone who finds it repugnant.
Committing the act would require some type of strength and sacrifice.
If she engaged in the bloody senseless slaughter of her own family (which I gave example of earlier) my love would be diminished to the point of non-existence.
Committing the act would not only require a lack of almost all of the admirable traits I admired in her but it would be strong evidence for the presence of traits I abhor in anyone.
I would have to reconsider "who" she is and under most circumstances this would most probably mean a complete loss of love for "who" she is.
There would be nothing left worth loving, she`d be dead to me if not hated.
In other words it seems most people believe their love for their children/family to be practically genetic in nature.
I don`t.
