There was a murder a ten years back involving a contract killing of a young woman, a Sikh, I believe. She was persuaded to go back to India, where she was murdered by gunmen hired by her mother and uncle in Canada.
Despite the killing, her uncle is a respected member of the Sikh community where he lives, and still an elder at the Sikh temple. Ten years later, the Indian government is still trying to extradite him, but the Canadian government, to their everlasting shame, has continued to throw roadblocks in the way of extradition, most likely, one assumes, because these are prominent people within the Sikh community and the government is afraid it will cost them votes if they let them be extradited.

I would put it to you that if a mother or father were known to have killed their children in Canada they would be shunned by the community, not held up as great and respected members of that community.
