Hi, I read a lot of manga but now I am looking for specific subject manga can anyone recommend anything matching it:

I already read thru Bleach, Naruto, D.gray-man, Vampire knight, Soul Eater, Kekkaishi, Gantz, Full Metal Alchemist, Full Metal Panic, 666Satan, Trinity Blood, Kyou Kara Maou, Hellsing, One Piece, Mai-Hime/Otome.

So looking for:

1. main (Male) character kidnapped for by evil-doers/good-doers for his powers. (Point on kidnapped -aka against his will)

or

2. main (Male) character kidnapped and brainwashed by evil-doers but then gets free of mind control (eventually)

or

3. main (Male) character is likeable anti-hero (aka villain) doing evil till he realized his mistakes and becomes a do-gooder although controversial one. (Please don't recommend something too sweet and corny for this!)

The said character is a male not a poor helpless girl victim or xena/buffy-like female.

I am looking for action/fantasy/scifi. No purely romance/comedy but action mixed in like Gintama (I liked DN Angel too though). Definately not hentai although soft yaoi will be ok. I prefer good ending not necessarily happily-ever-after onces but good. I hate stories like this - poor tragic hero had a crappy life but he wasn't weak and fought hard to get what he wanted, his friends died/betrayed and then he died/went mad/lost. The end.
I prefer main hero to live but if he has to die its because he saved his friends and accomplished everything he set out to do and he died to get his victory.

Any recommendations?

🤣

Cant find anything directly specific
Here the character is framed and placed in prison, (against), he then hs some special power with which he has to kill for (which he is also against), he does get fooled a lot.
Deadman Wonderland
Altough he is a good guy, his methods are questionable.....
Ultimate!! Hentai Kamen
Though you did specify, male, the lead here is good example of some Ani-heroism
Franken Fran
The main character, the guy with the blade on his feet

was brainwashed into killin people

Ichi the Killer
Jormungand
Kurohime
