Does lighting a candle for a dead person who's family is angry at you make everything better?

I lit a candle at Lourdes to honor all the students who passed away at my HS. The picture of the candle was posted on the high school's FB site. A friend of a late alumni saw the candle and was inspired to reach out to the mother of this deceased student and comfort her mother. I did not contact the mother or the friend in question. I played no role in her decision to reach out to the mother. The mother and the family were really angry at me and they hate me. I didn't mean to harm them. Because of my candle, the mother was comforted. Does the candle and the kind act it brought, make everything better again?  I do not feel I can forgive myself until this is forgiven by the family.
