Is it normal that i think this deeply into mental health disorders a lot?

I understand. It depends though on the severity. It's a "disorder" because its not a "disease" - many things are not well understood and don't have a physical source, like a tumor or mutation. Now, my bf is bipolar and has a lithium imbalance, but his bipolar cousin does not. My bf manages without medication - occasional mood swings, but he know how to handle them. His cousin can't function without meds because she's so depressive.

In my opinion there are occasions when a person truly can't handle their situation due to a mental disorder. But many (or most) are able to handle themselves, or at least recognize and control their symptoms, and so should not be excused for their behavior. A single outburst is one thing. But a repeated, known negative behaviour (pedophilia) in inexcusable because either the individual chose to continue it, or they chose not to seek help.

However, it also seems that mental health is the go-to for impossible defense cases. Oh, you murdered your wife, and there are witnesses? Claim mental health. I'm sure there's the occasional true story, but it seems that the excuse is over used.

a pedophile is the mental health term, a child molester is someone that has actually acted on it. 2 totally different things. there are innocent people that get disturbing thoughts about children but they have a conscience so they do not actually act on it. some people have a conscience some don't. the ones that dont are the ones that act on it. there are more pedophiles around than you think. a lot more. but the word has been given such bad reputation everyone is scared to talk about it. and some countries you have to actually hurt a child to get help from a psychiatrist...

I'm confused by them too. I know people who have certain mental disorders and when I get to know them, it almost seems like it is a part of their personality to be depressive and negative or hyper and bubbly.

It has to do with sociology I guess, that is what is socially acceptable so that everyone in the world can coexist peacefully, in theory... So yeah I don't really know how they sort those mental disorders, cos I thought the same about pedophiles. They go to jail I think? but maybe they should (or they do) go to a therapist about it. But, their mind is not such that they can't understand rules, they just have an amoral attraction.

I understand what your saying and it makes sence to an extent. Mental health traits become disorders when they make the person become dysfunctional. If you look into the mental health text books everyone will qualify for one or usually more "disorders" because nobody is perfect.
