The Villain didn't ask for a Redemption Arc (Isekai, Lite LitRPG)

Hale's last memory was jumping into the river to save a girl. Now, he awoke in another world filled with magic and mana. He was trapped in the body of an evil dark mage who had just lost a battle—one arm severed and his body covered in countless scars. And it seemed this was the result of a failed transmigrator who had inhabited this body before him. As if things weren't bad enough, he was bound to a system that forced him to atone for every single sin this body had ever committed! --------------------------------------------------- "Do you remember your name?" "No. But the kid called me Hale Wallace or something, didn’t he?" "So, you've also forgotten that you are a traitor to Berula, who then became a commander for the enemy nation of Seki, once led an invasion against Ember, and are a loathsome, feared Necromancer who was just defeated and presumed dead by Sword Master of Berula?" "...Yeah." "Then I suppose you've also forgotten claiming to be some kind of ' transmigrator from another world'?" Hale’s jaw dropped. Was the previous owner of this body also a transmigrator? --------------------------------------------------- What to expect: ● Strong to weak MC (just kidding, he'll be strong again) ● Plot twist and drama.  ● Lite LitRPG and GameLit ● Found family ● Romance subplot, no harem. This story takes place in the same world as The Uprising of the Hero Party's Underling, but it won't have any impact during the early stages of the plot.
