Well, that's kinda the point. Mental disorders a lot of the time doesn't make logical sense. Sure there are certain expectations to what an illness might entail, but a lot of the time random emotional or some times personality shifts happens. This is especially true with ADHD and Psychotic tendencies. You can be looking at flowers and relaxing, but then a trigger, whatever that may be, sets you off. Causing you to suddenly plan out how to kill your parents and dispose of their bodies. Sometimes a trigger isn't even necessary, sometimes it just happens.
