Do you believe in capital punishment?

I think it deters crime. I think if it was used more and criminals had less appeals it could be more effective. Its more of a criminal justice issue than a human rights issue. Read up on Singapore, its crime rate and how its used in that country. They execute more people than any other country in the world and there crime rate is remarkably low. I googled “Singapore crime rate” and found a lot of information that show the effectiveness of capital punishment in that country. I would like to hear your opinions on the topic.
