Well I feel the decision would make a difference as people would easily identify the rapist and take precautions instantly. But, the mark should be made visible no matter how hard the rapist tries to hide it, like on the neck or somewhere close to the face or eyes. This would alert people. This should be done and passed as a law.
It’s a good idea to tattoo the rapist who rapes a minor. Social embarrassment may set an example to deter others from thinking of raping someone.
A tattoo mark would help in recognizing the person for sure and cause him lot of social embarrassment. When you are publicly identified for your mistake it surely hurts. Why only for raping a minor every person who rapes anyone should be tattooed.
It’s a mental condition. It would help to identify the culprit. They should be also castrated and that would solve the problem at the root level.
Tattooing a rapist is a good idea surely. The culprit should be publicly disgraced to set an example.
