JUSTICE. I think the picture says it all, the death penalty is simply a butcher but not implementing something just for a human being who has committed a crime. The negative effect of the cerement in the background emphasize the concept of the cartel, without being explicit.

Death is not justice

Our 2010 project asked for the universal abolition of the death penalty.
For us it’s simple. The death penalty is a violation of human rights.
Article 5 of the Universal Declaration of Human Rights states: “No one
shall be subjected to torture or to cruel, inhuman or degrading
treatment or punishment.”
How does that fit with beheading, stoning, hanging, lethally injecting
or shooting someone?
