As a parent, I have to agree with you in your feelings. I live in Texas and we have a death penalty in our state. Although the state is criticized for this, I don't think the victims criticize it. It's called justice.
But it's not up to the Christian congregation to physically execute these wrongdoers. Divine justice will come at it's due time. Jehovah will read the hearts of all wrongdoers and act accordingly.
