[Avodah] mitzvot and sins cancel

[Eli Turkel]

I was basing myself mainly on the Gemara, and brought the MY L'ravcha
D'milsa. In any case, can you provide a source that Tzedakah cancels out
Aveiros?>>

Certainly teshuva cancels out sins.
There is much discussion of the Rambam who talks about weighing sins
versus mitzvot
to determine who is a tzaddik. He then stresses that one should do
teshuva between Rosh
Hashana and YK. Many ask the question why do teshuva - just do more mitzvot.
According to MYG the simple answer would be that teshuva cancel
aveiros while mitzvot
don't. While a reasonable answer it is not the only answer given. So
it would seem that
not everyone agrees.
Another question in the same Rambam is why is tzedaka any better than
any other mitzvah in outweighing aveirot.
