Good can never be equal to what is bad! One can destroy their bad deeds by doing more good deeds. Allah loves a servant who constantly repents.
“And not equal are the good deed and the bad. Repel [evil] by that [deed] which is better and thereupon the one whom between you and him is enmity [will become] as though he was a devoted friend.” Quran (Surah Fussilat, 34)
