Ethics is the study of right and wrong, of which actions we should and shouldn’t perform. Not all the things we do are morally evaluable of course. If I trip over a carpet something has happened to me I haven’t done anything. The behaviours we choose, our actions, are the only behaviours of ours that are morally evaluable: in choosing them the choices we make are moral choices.
