No, he isn't, because he was unaware off what it did to Chase, because he really wanted to help him. This story will actually explain his character.
And no, it doesn't change the fact that Chase got hurt and got dog trauma.
But honestly, Chase in a different way is also really bad, and he knows what he is doing, which kind of makes it worse.
1. Tried to shoot a paparazzi.
2. Tried to shoot Josh.
3. Tried to drown Josh.
4. Kicked Henry out of a helicopter that already lift off.
5. Bit off another actor's tongue.
All that in that short amount of time.
So what do you call him?
The only reason Chase is the way he is is because of his brother Grayson and he is not even remotely close to being as god awful as Grayson is. If you were raised surrounded by disgusting creatures like Grayson that were constantly trying to kill you, you’d do what you had to in order to survive and have major trauma and inability to trust others. Grayson also said he’d r/pe their younger brother in case you forgot.
If anyone needs a reminder of what Grayson Miller did to his little brother:
1. Dropped him down a chimney when his brother was around 4-6 and his brother ended up with a broken arm.
2. Locked him a closet.
3. Pushed him in front of a moving bus when his brother was 9-11 resulting in a broken arm and a broken leg.
4. Tried to force his brother to sleep with a dog saying “a hole is just a hole”.
