You are kind of going overboard B214. I was referring to Issei's views on Jeanne in respect to Striker's suggestion she become his knight. Not on her overall viability as a good character, and whether Issei is an example of absolute justice. Issei wouldn't like her, so that pretty much kills all likelihood of her being in his peerage. It's been shown quite a few times that if you threaten children in his presence, he will not forgive you, and I doubt she is just misunderstood like Kuroka was anyway.

Besides, you can't really compare Issei's activities to people like Jeanne. No body is perfect, and the Three Factions know this. That is why the people who make mistakes, yet didn't do any real harm, are given second chances, like Cao Cao and Vali. People like Rizevim, Euclid, Walburga, Jeanne, and Hercules take it to the next level by threatening innocent people. These people are either arrested and disappear or just straight up killed, they aren't meant to be redeemed.

This isn't Naruto where all the villains are just lost souls. Some people are just evil and either need to be put down or put away.

Some people are just bad. The world isn't black and white, there is grey, but that doesn't mean there isn't also some black and white. It doesn't have to be complicated.
