I (and I suspect victims of crime) sympathise with this POV. However, I'd encourage you to also think about it from a larger perspective, like a government: what would be the most advantageous path for a society to take in dealing with crime? If you take such a larger perspective you'll see that individual justice is only one of several important factors.
I don't have time to explain further. But one analogy could that nobody likes to pay taxes themselves, but many accept that taxes in general (if well-spent) can be a net positive for a society/country.
Exactly. It’s hard to feel emotionally that prison abolition is right in the face of an individual case. You want justice! But if you look at the system as a whole you have to conclude that, on average, justice isn’t really being served. The tax burden is unjust to the tax payer. Poor conditions and long sentences are unjust to incarcerated people. Strange sentencing rules and prosecutory practices (people can get more time for petty theft than rape) are unjust to people who want justice.
