Sarah Lynn-Bojack opinion?

so a lot of people blame bojack for Sarah Lynns death but I think she was going to relapse either way. she had liquor bottles ready for consumption and coke in her walls so to me it seemed like she was just waiting on a good excuse to fall back into her old habits. also when they were on the phone bojack was only talking about partying he never said anything about drugs thats what Sarah Lynn assumed. bojack should've been more supportive as a friend I agree but I dont think he is guilty.
