got robbed and wanna hurt them so bad

i was in a train, going back home then 2 guys grabbed my hand and 3rd one grabbed my gold chain, my grandma gave me that chain and she passed away (they did not use weapons tho)

now im full of anger and just wanna torture and put an end to their miserable lives and im sure I could do it but I know ill be in prison for the next 10 years

how to control these anger? Im thinking about it everyday since this had happened and im praying that I see the guys one day

what should I even do? I cant move on
