did you even read my comment? there are different TYPES of insanity. let me re-do this for you.
insane (what I'm like) = roleplaying killing people, so we can have a laugh, drawing scary pictures, raging, animations of death, pictures of death, and just being plain idiotic and stupid! 
insane (real life) = no roleplaying, no laughing, no "pictures" or "animations". real rage. real voodoo dolls. real deaths. real insanity.
insane (children/childish/mental disorder) = being completely mental, fooling around and never acting your age.
roleplaying killing people, so we can have a laugh, drawing scary pictures, raging, animations of death, pictures of death.
(That is not insanity that is morbid.)
no roleplaying, no laughing, no "pictures" or "animations". real rage. real voodoo dolls. Real deaths. Real insanity.
(I guess that's some kind of insanity.)
Being completely mental, fooling around and never acting your age.
(Immature behaviour.)
None of the things you listed are types of Insanity.
