Illinois abolishes the death penalty.
Since the 1977 when death was reinstated the state has executed a dozen people with the last one being in 1999. In 2003 the then governor, who was a republican, put a moratorium on it and commuted sentences. The current governor seems to have been in support of capital punishment, but passed the ban in the end.
North of the border, capital punishment hasn't been available in Wisconsin since 1853.
Overall I think getting rid of it is a good thing. Out of the modern world, Japan and the US are the only countries to retain it. Eye for an eye and acting in revenge is something to rise above.
For that matter, I don't think it's much of a deterrent. If anything the death penalty is like an ejector seat sparing the person from being forced to spend the rest of his life in prison.
There's also the issue of justice and evidence and whether accidentally executing a single innocent person is worth putting to death a bunch of guilty people.
