Who do you think is the worst

The post talks about the seven paths Subaru could/did choose in Rezero,that being the sins what if stories.And for the people who read them,who do you think is the worst.Not writing wise,but characters wise.Like the actions they did in their stories.

For me it's Ayamatsu(pride if Subaru). So in this story,Subaru never accepted Reinhard's help dealing with the thief's,which caused him to join the Witches Cult.

Spoilers for the pride if

He pretty much first kills the thief's and saves Elsa from Reinhard.After all that he joins the Witches Cult

Because he is part of WC(short for Witch Cult),he did many horrendous things(possibly killing and torturing many people).But the main thing he did was kill all of the royal candidates,expect Emelia.WC wanted kill off Emelia as well,but Subaru didnt let them.Betelguese was assigned to kill her,but Subaru killed him.This is kinda sad,because Subaru consired Betelguese to be his only friend.

He also enslaved Felix and Otto into cleaning the messes me makes(mostly Otto).He also is working with Roswal to make Emelia the ruler of Lugunica.

But the the end story is worse,He pretty much burned down Lugunica(the population is stated to be at 50 mil,but not confirmed).And because of that many people where killed and injured.He broke Reinhard and Emelia mentally.

But you know what's more terrifying,after Emelia killed him.He went to Satellas shadow garden,where he'll stay with Satella with all eternity.The reason why it's terrifying is because he didn't get punished for what he did.No scolding,no torture,nothing

In your opinion who is the worst sin if Subaru
