It's a strange issue to discuss though that's the problem. Like, our Imam, every week in his sermon, talks about topics relevant to 99% of the men present. Honour killings, paedophilia, terrorism - muslim communities have been touched by all three - but who is it relevant to? the 99.99% of people in the masjid don't need to be told about honour killings, they already know it is bad.. so who to address.... there might not even be a single person with such inclinations in the Masjid? And of course, our scholars, do condemn... but do such people read their condemnations? The best thing is probably to have strong family structures with people unafraid to seek help when they see troubled family members - with a good wider Islamic community support structure in place... how to achieve that? That is a tough question.
It Is narrated on the authority of Abdullah b. Mas'ud that the Apostle of Allah (may peace be upon him), observed: He who has in his heart the weight of a mustard seed of pride shall not enter Paradise.... Sahih Muslim, Book 1, Chapter 40, Number 164
