Does ‘right’ mean ‘no punishment’ or ‘punished forever’?

Neither!

Because it’s written that:

‘what is right?’

“Why don’t you judge for yourselves what is right?” (Luke 12:57)

There is punishment but it’s ‘not’ forever. Rather, it’s ’till’ you’ve paid your last penny (limited -duration of ‘time’ according to your sins)

“As you are going with your adversary to the magistrate, try hard to be reconciled on the way, or your adversary may drag you off to the judge, and the judge turn you over to the officer, and the officer throw you into prison. I tell you, you will not get out until you have paid the last penny.” (Luke 12:58 – 59)

Who said this?
Lord Jesus Christ

P/S:
The word ’till’ or ‘until’ signifies a ‘limited time’
