There are many people who agree with you and consider the things most people do absolutely absurd. I've personally spoken about how I view jails as inhumane unconditionally and how reforms should be made towards actually rehabilitating people who hurt people rather than letting emotions run wild to the extent of throwing people in cages as punishment because "they deserve it", as if their moral opinion on "deserving" something actually matters as opposed to what's actually best for the world. It's okay for them to be upset and have feelings. It's okay for things and people to offend them. Things and people offend me too. I'm plenty emotional. But I've always considered it inappropriate to run the world on that because we enter the same kind of awful decision making process that caused criminals to rape and murder people themselves. We're just on the other side of it, so it's cool. Socially, at least.
But there's no point in vocalizing pretty much any of these thoughts because they're going to be lost on nearly everyone. People are just going to make even more assumptions, get even more upset, start yelling about how everyone who doesn't agree with them is a monster, and so on. It doesn't accomplish anything as there's no legitimate discussion that will take place. If even one person such as yourself is around to have somewhat of a chance of agreeing, it doesn't even need to be said anyway because you'll already know and won't need to discuss it.
As such, there's no true point in expressing some thoughts until they gain a little bit of mainstream momentum. Instead, sit back and try to enjoy what you can to the best of your ability and wait for the future to potentially open up realistic opportunities.
Our justice system came a long way. Originally justice is about payback, an eye for an eye, and that is justice, then it became about what you said, it's about rehabilitation, notice the some of the jails are called "penitentiary", criminals used to be put in cells with trees and whatnot to allow them to meditate on their crimes and repent. It didn't work well, some of the criminals went insane, and now our current justice system is largely a capitalist ones, "paying debt to society" as it were. Crimes are committed against society and actual victims are often not factored into the course other than mere witness, in our justice, the victim is society, and you either way your way out or work off your debt as laborer.
What you are talking about (or want) is probably restorative justice. It is a new concept (to white people) and is seeing limited use in some of the cases in North America, and I agree, that is the way of the future. However you must also accept the fact that some people may simply be unsuitable for a life among other people. Ariel Castro's value infringe on rights of others, you can only repent when you think what you did is wrong. People who refuse to see their crime as wrong doings are unsuited for restorative justice and ultimately like the judge said. unsuited to live in society.
