Incorrigible adjective MAINLY HUMOROUS

An incorrigible person or behaviour is bad and impossible to change or improve:
an incorrigible liar/rogue

So it is quite reasonable to use it; below you have some context:

1. A fresh wave of accusations against his incorrigible wife.

2. Incorrigible to the last, the high priest of scandal has even turned his worst moment into a punch-line.

3. Philosophy has an incorrigible bias towards thinking.

4. Incorrigible flirt.

5. Incorrigible young offender.

It depends what you actually need, maybe this:

Scape•grace (plural scape•graces) noun
Mischievous person: a lazy, mischievous, or irresponsible person, especially a child

Or this is nice:

Redeemable, reformable
