<human>: Can you succinctly summarize the text in 1-3 sentences?

(Throwaway account for the first time ever.)

My step-brother is a bad person. Not because he injects meth. That's bad, but there's an explanation, a disease, an addiction that causes it. He's a bad person because he drove stoned with his amazing son in the car. He's a bad person because he broke a cabinet with his (pregnant) girlfriend's face. He's a waste of space because he leaves a path of destruction and pain everywhere he goes. 

The stress he puts on my step-mom and dad is unbearable. A few weeks ago, my dad's blood pressure was at stroke levels. All because of the incredible strain this waste of oxygen has placed on my dad's marriage, finances, confidence, and happiness. I think the parents have cut my step-brother off for good now, but they have said that before. 

Last week, they drove the asshole to a rehab clinic. He wouldn't check in. So, they left him there, hoping that if he was abandoned he would have no choice but to check in. Instead, he told the clinic that he likes drugs more than his family, and hitch-hiked back to his "home." 

At this point, there are 3 possible outcomes:

1. The step-brother overdoses.
2. The step-brother goes to jail for a very long time.
3. The stress kills my dad. 

I'm hoping for number one or two. Does that make me a bad person? Maybe.
<bot>: my step-brother's shitty decisions are causing incredible stress that is threatening to kill my dad. I feel bad for hoping that my step-brother just dies or goes to jail before the blood pressure kills my dad.
