Um... he's an abortionist. Of course he's going to kill again. To take a line from the insurance commercials, it is what he does.
It really irks me when abortion clients are called "patients." That terminology, unfortunately, helps the abortion industry pretend that it provides medical services. It does not. There is no medical purpose whatsoever for the use of abortion as birth control.
