Melizabeth: He interacts mainly with Elizabeth by harassing her, but he is not really the problem when the victim lets him do as he pleases And then she falls in love... It is heavily hinted that she is some reincarnation of Liz and yet she is like a completely different character. Suddenly when she realizes and feelings, she starts angsting because of a lover who is supposed to be dead...
. Elizabeth...
Ban: Nothing major, him trying to kill Meliodas to revive Elaine was a mistake but I find it understandable somewhat.
King: I got that he has been unlucky in his life but, unable to fulfill his promise to Diane, he erased her memories, then he trusts the HolyKnights and decide to kill his companion Ban, knowing very well that they all backgrounds they don't want to talk about. Now that I think about it, it's kinda weird that he kept lamenting because of Diane since he is the one who erased her memories in the first place.
Diane: Being used badly for romance stories which are not very good, I wonder what was the point to make her fall for Meliodas in the first place. Why does she think her pigtails are part of her charm when she is so obviously better with her hair down? ;bored She should change her hairstyle, her Giant clothes are a proof that she has not a good fashion sense

Gowther: He is perfect. The incident with Guila made me like him even more.
Merlin: Currently my 2nd favorite Sin
, though I am more confused about Magic and stuff because of her and her apprentice.
It's not his fault at all. King decided to erase her memories, was lamenting all the time and didn't confess when they met again as Deadly Sins twice, now that she remembers for some reason, he is missing and Ban helped him, Ban did nothing wrong.
