That’s not really a correct assumption at all. Some suicides are well thought out and planned, but many are also very impulsive and sudden. There is often no way to know which is which, and saying “he made peace with that a long time ago” is a huge assumption and a possible gross characterization of his and other similar suicides.

The fact that he called his family over to help him clean could have meant anything from him working to overcome his issues but temporarily being overwhelmed which made him make the the sudden choice to tragically end his life, to as far as him trying to “get back” at by his family members by making them find his body (I’m not AT ALL trying to say the latter is true, just trying to make a point about the huge range of possibilities scenarios, about which we have no idea).

Unless we have substantial information about the situation and intentions of someone who killed themselves it’s not fair to them, their loved ones, or people in similar situations to make assumptions about their state at the time the ended their lives. That’s all I’m saying.
