I guess it depends on how you read it. The way I read it, I think Danton's father feels he needs psychiatric help, which very well may be true. There are plenty of cases where people have mental health problems and create situations and problems that don't exist. What if all the alleged abuse is just in Danton's head? What if he estranged himself because of some things that only exist in his head? It's certainly possible. And if that's the case, then he really DOES need help. Not jail, but psychiatric help.

And maybe Danton was planning on killing Frost and Frost just doesn't want to believe that it's true. Is that really a far-fetched idea? Especially if you're good friends with the guy? What if one of your good friends got arrested for plotting to murder you? It's not likely that you would believe the charges. However, if the evidence is solid and true, then that's what happened. Just because the alleged victim doesn't care, it's no reason to drop the prosecution. This is murder we're talking about here, not petty theft or battery. And again, what if the prosecution has evidence that proves the case beyond a reasonable doubt? What if, in the end, Frost realizes that Danton WAS trying to kill him? I bet he'd be pretty thankful that they continued the prosecution of the case despite his initial reactions.
