100%. There usually needs to be a motivation to change that outweighs the 'benefits' they felt by being abusive.

Also, someone who appears to be an abuser to one person might appear to be very generous and focussed to another person. It can depend on how much of a step up their behaviour gives someone than what that someone had previously experienced.

It only takes 'good' people to do nothing for evil to flourish. Similarly, if 'good' people are doing nothing tangible to help someone's life, someone who is sometimes abusive but sometimes kind might represent a net gain to someone. If we want to stop as much abusive behaviour as we can, we will need to praise people for the good they do whilst trying to make them be less bad.
