I wouldn't say Minaje was a great victim. He was at a certain extent but his selfishness and cruelty overshadowed it. Minjae being selfish and literally killing a person can't justify him being a victim. And not only that, he ignored Lee Sunhoo who was in much worse position then him but choose to ignore. It just show how selfish and cruel he is! And, he never remorse for his wrongdoings.
My first sentence literally said everything what you are describing. He being a victim is on certain extend (literally this is in my second sentence) that don't make people do so many worse thing that what he have done. I never said he is not victim but said not a "great" victim as in his victimized is nowhere near what he did to a person who was nice to him. I honestly don't feel sad for him after what he done to that child. Just because you were victim in the past doesn’t make you any good person.

They were all victims who, unfortunately, repeated the cycle.
