Any suggestions on which is worse zoophillia or necrophillia?

Both are unhealthy: Family members may be very upset if their deceased loved one's body has been violated. On the other hand, sexual involvement with an animal is abuse of the animal. Any one who acts out zoophilic or necrophilic fantasies harms both themselves and others. Even if one is not acting on the urges - it is taking the place of meaningful, loving sexual intimacy.
