For me it comes down to whose crimes are the most severe in which lives are spoilt, the crime has long-lasting effects on the victim and "sorry" can change little. I see Dadisa's actions the most like this. Anandi torture, what she has done to Basant's wives and then what she did to Gauri.
Then Jogia. However much Anandi moves on the pain of what she went through can never be forgotten and the same can be said for Gauri who I'm guessing is now living with their child in the city so technically the child suffers too cos Jogia ran away. Whatever Sanchi is mean selfish bratty but she has feelings for Jogia (can't for the life of me think why all these girls keep falling for this guy) and they've been shattered too because of Jogia's haste and stupidity so now she is on a path of destruction.
These two are the characters that have actually ruined a lot of lives.
