HaRav Yosef Ovadia on Shulḥan Arukh, OH 606:2
Alright. But how do I choose those ten Jews who come with me to the other person's grave? Or are they chosen by someone else on my behalf?
Say, I'm a man who has groped a woman. Later, she has killed herself. Now, I want to "repent", but only with half of my heart. No, seriously -- a quarter of it is the maximum I'll give. Basically, I just want the complaints about my behaviour to stop.
So I choose a minyan of 10 Trump-loving Jews, who all love doing what I do -- or who are at least craving the courage to do so --, and go to her grave with them. They forgive me on her behalf.
Am I forgiven?
