Vader isn’t an asshole.

Vader is a broken demon.

Raised a slave, he needed therapy not dogma.

The man who found him understood this, but fate didn’t play favorites.

Anakin was manipulated, twisted, used or abandoned by every person he ever met.

Except Luke, Luke never gave up on him, and more importantly, Luke understood him.

He was raised similarly to Vader, without the same abusive and destructive history.

However, Jenny is absolutely a full blown asshole.
