"Peruse can mean 'to read something in a relaxed way, or skim' and can also mean 'to read something carefully or in detail.' Peruse is thus a contronym because it has multiple definitions that seem contradict each other." https://www.merriam-webster.com/words-at-play/peruse-usage
We don't mean "destroy 10%" when we use the word decimate anymore, I get it. Natural language, migration of meaning, subjective denotation etc.
