Ah, I see. Thomas never "faced the issues" which confront the oh so superior "modern man". Has truth changed? Has good and evil changed? Has mortal sin changed? No, because eternal truths are just that--eternal, outside of time and space. Aquinas would be every bit as brilliant today as he was in the 13th century. You have said nothing to contradict the wisdom of Aquinas' teaching other than the typical modernist canard of "we live in a more complex world".
