Donald Trump seems to have a passion for cruelty, often publicly celebrating his investment in violence as a source of pleasure. Those tendencies represent symptoms of a broader American sickness.
Trump's decision to end the DACA program, as well as his support for a bill that would drastically curb legal immigration, would hurt the US workers he says he's trying to help.
From south of the border, Trump seems to be using DACA as a diplomatic weapon in his ongoing power struggle with the Mexican government. That just hurts 800,000 people and helps President Peña Nieto.
