Is it normal my husband's new tough love rules are making everyone miserable?

He took my adult son's car off him.He also is trying to ground evan from leaving his room even to pee. He hides evan's debit cards and license to ground him and makes Evan look all over for them.My son deserves that car. because he takes care of me and watches his sisters kids all the time and goes to school and work.But my hands are tied because I am not in the best of health and I have to do what my husband wants. My Husband is trying to force him and me to drive with him. My husband is a bad driver and he gets in wrecks all the time.My adult son is frightened to be around him because he acts psychotic in the car and follows evan everywhere and makes a scene. Evan wants to leave. Then my husband told him he will quit paying for college if Evan leaves. Then he screamed at Evan for hours for being a leach until evan cried.He is making it difficult for evan to get to work and trying to get Evan fired. He also is trying to force him to break up with his gf.I don't want to drive with my husband either.Evan said he is sick of him F******G up his life and me covering for him and that it is not ok that his dad is allowed to be abusive and he is supposed to sit there and smile.Evan is now an agnostic which really cheeses my husband off. I try to help Evan when I can but have als and can't do a lot of things.

Evans defies his orders and pees anyway and drinks coffee this gets him really mad. So he blocks his door so Evan can't leave. My husband is very religious and believes causing tons of pain and hardship and in our son's life will toughen him up . I don't agree and don't like it. He gets mad and says I am not being loyal to our marriage vows.Which hurts me I shouldn't have to choose between my son and my husband.
My son gets whiplash everytime he drives with him and he won't drive with him. But my husband says he has to depend on him for a ride now but then yells when he has to take him to work. He also yells if I let evan use my car.

Evan says he roughs him up and worse when I am not around. But my husband his pastor says he is making it up. I dunno who to believe.
