Hard to convey my feelings, the massacre of the Fogel family including 3 children.
I believe in the need to consider the death penalty or at the very least life imprisonment with hard labour and solitary confinement with no chance under any circumstances of release for animals that can commit such a crime. Why should we pay to feed them and enjoy the company of other inmates playing soccer, playing cards watching movies, mobile phone calls, family visits even University courses and degrees, these are some of the benefits that have been given to murderers.
Not only that you have the risk of another poor Israeli soldier being kidnapped in order to be used as a bargaining chip in return for these animals. In this regard see Samir Kuntar, for another example of many that were released.
