Son, if tomorrow somebody kidnaps or rapes your child, you, like a keyholder of your child's freedom, will be responsible because you haven't cared enough, right?
When criminal activity is done, it can not be justified just by the mistakes of the victims.
Human beings are weak creatures. We all make mistakes and we all pay the price for it in one way or another, but this still doesn't mean that somebody who took profit from our mistakes through criminal activity has the right to avoid punishment so he/she can continue freely to the next victim. It will never be accepted and tolerated by the human community.
Freedom with responsibility strongly implies ethics of justice.
It will never be real freedom (with responsibility) and real decentralization under these circumstances where cybercrime became the third "economy" in the world, just because it can.
Pablo is not dead.
Taking responsibility by yourself doesn't mean allow the scammer to roam all around free and keep stealing the money, crypto network is transparent so they will get caught if they are sending it to any exchange or someone else who verified their KYC so its more easier to trace the scammer with blockchain technology.
