My father (an ex-English teacher) used to always say something like "concision is rarely wrong, unless it ruins precision."

"And when she was bad, she was very, very bad."
Let's all agree that using "malicious" or "malevolent" would "degrade the semantics and syntax" of the sentence.
The number of absolute statements you can make about the English language is very close to the null set.
Or perhaps more appropriately:
"The truth is rarely pure and never simple. Modern life would be very tedious if it were either, and modern literature a complete impossibility!"
It can also be used quite stylishly. Most words can.
