Hate when people say this. The monster does horrible things to innocent people, whereas Victor doesn't really do anything out of malice. And everyone always talks about what a fine gentleman Victor is every time they mention him.
Moreover the quote is basically, "knowledge is repeating a fact you heard somewhere, wisdom is repeating a glib misinterpretation you heard somewhere"
And I gave my heart to know wisdom, madness and folly, and I perceived that all is vanity and vexation of spirit. For in much wisdom is much grief, and he that increaseth knowledge, increaseth sorrow.
