I look at it like this, If you can't care for an animal find some one willing to try. Some effort is better than no effort. I'm not experienced snake care provider however as with ANY living thing if it is sick a doctor trip is in need! I currently took in 3 snakes that were in very bad conditions only because I could do better with no knowledge than what they were doing! That is how I found this site. Sounds to me like you both should be reported for allowing this snake sit and suffer from mite, a unhealthy tank, and bad home period! Erks me to no end when people get pets and just don't take care of them. While others sit and allow it to happen. Yes you are allowing this snake to be in the situation it is in. Why ask for help if you are unwilling to do anything?
