Is this a cold hearted thing to say to abusive parents?

my friend grew up with abusive parents, she doesn't love them at all but only goes back to them whenever she needs anything from them. She only uses them, doesn't care for them one bit because they've hurt her tremendously in the past. Despite the maltreatment, her parents still have a heart to help her. She said her parents were "good for nothing" lazy retired old people who just sit around , do nothing, contribute nothing to society sitting around, never paid taxes when they were young or old. She called them a "waste of life"
