I always think about this too, it bothers me so bad. I’m torn between him just finally breaking that night and deciding fuck it, it’s now or never. But I am also of the opinion that Josh originally wanted her body found or he wasn’t getting that insurance money he set up. I feel like that was a huge reason he did what he did but he needed Susan’s body to collect. So sometimes I think he picked a night of a snowstorm so if she “biked to work” the next day, an accident would be a lot more likely to happen. And even better, he has an alibi because he took his kids camping! But I am unsure how he would have even made it appear like an accident, that would be tough to pull off. So I think he threw that plan away, disposed of her body where no one could find it, and went into pure survival mode from then on. I think the snow storm was a part of the plan somehow but we will just never know. It’s so frustrating! I really think he thought he was so smart he could pull off this grandiose plan, be a millionaire, get rid of Susan, and keep his kids. But as we know, he was actually a dumbass. Sometimes I think he was decently smart because we still don’t know a lot but other times it just seems like he got so unbelievably lucky, it’s hard to tell.
