If you keep doing it, and it is serious, you haven't reformed, so no.
For example, Biblical forgiveness requires:
* you stop committing the act like theft, beating your wife
* you seek recompense like paying back what was stolen, pay blood money to victim's family
* then and only then do they have the option to forgive - and then it isn't mandatory for them, only recommended
This means the modern "just let go of the anger and forgive, don't punish them" is wrong. They have to stop doing it first to be forgiven, and your decision to forgive does not mean not punishing. In fact, they must face justice for forgiveness to happen - and the same is true for those doing immoral acts before God, too.
Otherwise, a mass murderer can both say they are right with God for seeking forgiveness and try to argue he shouldn't be put to death.
