Evil is an ambiguous word. It doesn't look like she did this out of malice. But greed or even fear (of saying no to hot shot prosecutors) - aren't all such reasons equally unwholesome?
Maybe, overcome with self-interest, she didn't view her victims as actual human beings. For example, if someone wanted to cut down a forest to build a strip mall on top of the land, they'd be dooming or displacing the animals (squirrels, insects, etc) that lived there, but most people would be comfortable with that.
Maybe she had dependents to take care of, and she felt that everything she did, she "did it for the family."
