Those are just a few of the words being used to describe the man convicted of killing British politician Jo Cox during a violent attack in June.
Thomas Mair was found guilty of murder, possessing a firearm with intent, possessing a dagger and grievous bodily harm.
Cox died after she was shot multiple times and repeatedly stabbed on a street in northern England.
The attack occurred just days before Britain voted on whether to remain in the European Union — Cox supported the "remain" campaign.
The judge said the attack was inspired by Mair's "admiration for Nazis" and ties to white supremacy. Witnesses say he yelled "Britain First" and "Keep Britain independent" during the attack.
It only took the jury 90 minutes to convict Mair. He's been sentenced to life behind bars.
