Murder for Honor?

I was surprised, rather shocked how the newspaper now-a-days carries at least one piece of an 'honor killing' every single day! It is even a shame to call this heinous act of crime as 'honor' killing. I am sure there is no honor behind these, but just ego. Ego of those who think their children betrayed them, ego of those who have no way better to prove themselves useful to the society! For me, it is unfathomable how anyone can kill their own flesh and blood!
Since the time one becomes a parent, all he or she thinks about is how to protect their kids, how to give them everything they want, how to just be there for them. And the only worry that a parent has is 'God forbid, if something happens to my child'. How can such a parent even think of harming that very child, for whatever reasons? There is nothing in this world, no amount of sacrifice you might have done for your kids, no amount of hurt they have caused you, that justifies this act. And to top it all, such people claim to be doing good to the society!!! I simply don't get it at all.
You know what would be actually good for the society? That everyone married as per their own wishes, and many people married in different castes and religions. That would make our country truly secular and safe. The children born of these marriages would be raised as just Indians, not a Hindu, Muslim or Sikh, or a Jat, Punjabi or whatever. They would be more tolerant towards the others' beliefs. That would make a tolerant society...may be even a loving nation, without any communal differences, and riots.
May we Indians get this sooner than later and for once, start thinking beyond caste, creed and religion to stand as one nation.
