There is no such thing as a painless lesson, they just don't exist. Sacrifices are necessary. You can't gain anything without losing something first. Although, if you can endure the pain and walk away from it you will find that now you'll have a heart strong enough to overcome any obstacle. Yeah, a heart made FullMetal. - Edward Elric
Why can't people see the bonding of LoV members? They all were a group of deviants but also have their convictions, they love and have mutual respect for each other. They were shunned, misunderstood, used, abused by the hero society which was supposed to be accepting and to be working for the people. I know that there are faults in the justice system but can be solved and the method of villains are also wrong but somehow the villain's seem to be in the right. Each of the LoV members backstory represents only one persons suffering, there could have been many people been exploited or be in any danger and seeking out for heroes but to no avail. Just like heroes trusting their dreams to the no.1 hero, the villains are also doing the same, sacrificing themselves because they know that their no.1 will bring a change not only for themselves but also for people of their kind. Dabi's past shows the dirty secret of "Quirk Marriages" and the current no.1 hero, Compress's past show the dirty secret of politicians, Toga's and Spinner's past shows the prejudiced thinking of the society which was laid down by the Hero society, Twice's past is just so heart breaking. Shigaraki's past is a sum of the members past. The only thing which i didn't like in the MVA arc is that Compress and Dabi's past were never shown but now I am content that they also had just reasons to change the world. Dabi's wish of having a family and being loved as a son even if he didn't inherited the ice quirk, Toga's and Spinner's wish of living in a world where they are accepted, Twice's wish of living in a world where he can trust others and in return they trust him are only wishes which the Heroes won't grant because they have been categorized as villains and we have been taught that villains are bad.
