I can try answer this since I have DID, the thing is, it all depends on which personality is in control at the time and if they know existence of the other personalities, an example would be Vic, she's rude as damn and said that for her it would count as a hostage situation, since she knows all the personalities, whereas Kuna, he doesn't know that the others are other personas, he thinks that they're other humans and would only call it suicide. Then there's Ridan who would say that it all depends on how they say it;
'Don't come closer or else!'
Would be be a hostage situation. If the person was saying something like;
'I'm going to kill myself.'
Then it would be intended suicide, don't trust everything I stated because this is only what myself and a few of my personas are guessing.
