As someone relatively new to the psych ward scene (last 5 years, in and out), I feel the only people who can't be held accountable are those born or inflicted with intellectual disabilities. Everyone else; regardless of their illness/instabilities, should be.

If they're harming themselves or those around them, despite how "insane" they (or others) might deem themselves to be, somewhere in that brain of theirs lies the knowledge to make a more informed and sensible decision.
Take yourself for example.
Despite how much you say the illness has made life hell, at least you're capable of a sound enough state of mind to identify the problem, you still possess inherent decision-making skills. If you're capable of at least that, you're more than capable of being held accountable for your actions. If you're simply incapable of fathoming the repercussions of your actions or just your actions in general, I'm not saying you should get a free pass, just more leniency.

I'm someone who suffers from a number of illnesses, and regardless of how much they may be impeding my ability to make a rational decision, I still have the knowledge ingrained to know what I'm doing is/isn't right. Even if that knowledge isn't present at the time. It's our responsibility as risks to back the fuck up when things aren't working up there, attempt to identify the problem, and try to do the right thing based on experience. Unless you're a small child, you have that experience.
