What does "vile" mean? Is it a more sophisticated way of saying "total" or "complete"?

"Vile" is similar in meaning to "repulsive," "horrid," "horrible," or "appalling." The speaker has used it here to disgust or approval at the man using taxpayer money to conduct useless science experiments. Ex: There was a vile man at the store today. He was very rude to the cashier. Ex: The criminal was known for having a vile personality.
