Very interesting that you brought that up!

Manipulation seems to be a loophole in this concept at first.

They did that with their own free will, therefore, it is not violence. Their freedom wasn't compromised and they were consenting to the act.

When you join the remaining core value, logic - it is apparent that such event would never take place. That is, unless suicide is the best thing to do for the flock.

Thanks for the comment, you've presented me with a worthy test.
