I am a Catholic and i voted for Trump . the issue for a Catholic is this - there are some  non-negotiables that have been written about in papal bulls encyclicals and the historical teaching of the Church rooted in Scripture and tradition. the third commandment say though shall not murder/kill (hebrew translates kill unjustly) The church has always taught the protection and promotiion of all life at all stages. Abortion - euthanasia, embryonic stem cell research are above othersocial justice issues becasue these issues involve the willful act of the destruction of life. Sin has 2 levels mortal which kills the soul and venial which darkens the intelect to Gods will.  Not all sin is the same. So when we look at moral issues we have to prioritize them in a hierarchical system. Immigration is an issue that is definitely a social issue we must address but there are a myriad of ways to address it and none of them are the willful destruction of the persons life.
