Yes, software can be used as a cover for abuse like in this case, but that happens because some people in power let it happen. For other pieces of software that have consequences for people with more power than prisoners, the society will not allow failures to happen. I only need to mention the MCAS software of Boeing 737 Max for a counterexample.
Software does not have its own will. Software is only allowed to make decisions on our behalf because we let it do so.
It is interesting that you bring up the 737 Max. I was actually talking the 737 Max in the context of software being both infallible and the perfect scapegoat with someone last week. The 737 Max is an example of how software was believed to be infallible (it wasn't) and was ultimately the scapegoat for a design flaw. That doesn't mean the 737 Max was something that happened intentionally. However, when the time came to assign blame fingers began pointing at the software.
I do agree that software has no will. It is a tool for facilitating our will for better or worse.
