What is being groomed this time?  

No pain, no gain.

Usually that means it is sometimes necessary to suffer or work hard in order to succeed or make progress.

However, the twisted perversion of no pain, no gain by Unholies is to inflict pain or torture as a means to gain power and control over the victim and steal intellectual property.  

Does this work?

There is no guarantee that if you inflict pain or torture you can get reliable information from the victim, which means there is no direct correlation between pain and gain.  

When a person intends to inflict pain, then there is a direct premeditation to cause harm.  

Causing harm, whatever the reason, whatever the gain, is abuse, unholy and a crime against humanity.

Causing continuous harm, whatever the reason, whatever the gain, is aggravated abuse, unholy and a crime against humanity.

All of which are immoral, illegal and crimes against humanity.
