, the difference between ethics and morals is often formulated this way: that ethics are the science of morals, and morals are the practice of ethics. But that’s a little too neat and doesn’t cover all the ways in which the words are used.

Trump is tough. Some might think that his being tough also makes him a bully. He is a decision maker and will be seen to be acting unilaterally because "he" makes the decisions.
