Arson benevolence?!?
改過自新
kai.ka.ji.shin
Literally: change – error – self – new
Alternately: Turning over a new leaf. Recognizing and working to correct one’s flaws and errors, and starting anew with a change of heart. New Year’s Resolution stuff.
Notes: This compound comes to us from the Records of the Grand Historian.

E.g. if you’re a sad yakuza, try turning into a sparkly businessman!
