In order to survive, I used to drug and rob women.
That's a horrible way to try to survive! Why would you do something so cruel?
I needed the money so I would take it from people who can't fight back.
It' clear you were in a bad time in life, but it's still no excuse to abuse people who were even more vulnerable then you were. It's also illegal.
It's fine. They'll never catch me.
Regardless of if you get caught, I hope you have learned from your past actions and won't ever do it again. Drugging someone so they can't stop you from robbing them is exceptionally cruel. If you still know the women you did that to, you should apologize and find a way to pay them back for what you did.
