Peter Singer's part is trying to eliminate the suffering of a child and his parents or an elder and his children by cutting their life away from future suffering. The equality front aims to reduce suffering by eliminating the killing of a living creature. The biological side also points out that by valuing one life over another, we are creating suffering, ultimately favoring one particular group over another. In response, Singer's side explains that in reality the guardian of the disabled person is left with the choice of not being forced to kill his or her family.
