Vader and Adam are not too

Vader never tried killing Luke the second he found out he was his son, while Adam has known Blake for a good chunk of her life and still stabbed her in the abdomen and was perfectly willing to kill her when she got in his way.

Vader was practically begging Luke to join him so they can take over the Empire together as a family and didn't threaten anyone in the process (except his sister near the end as a "maybe she'll be more receptive" thing). Adam was pissed that Blake left and vowed to hurt everyone she loves out of spite.
