One of the reasons my unincarnated friends gave for why I shouldn't commit suicide in this life was that the mindset I'd likely need to be in in order to do it might make me more likely to come back here. I'd likely have regrets and other things that could make me unconsciously not wan to leave. Thus I might not pop out "high" enough or for long enough for them to grab, as they claim to be living beyond what might commonly be called "the veil", the general area where poltergeist-capable spirits tend to reside. The extra jump makes it far more difficult for them to interact here for a variety of reasons. How valid those reasons are, or how true they all are is a matter of debate.
Thus if my goal was to get out and stay out, suicide was probably the worst thing I could do in my condition. That being said, I do think that there can be a lot of utility to suicide in certain environments. the problem being that, if you're just trying to escape a bad world chances are you're not going to and instead your refusal to try and fix things would contribute to every successive life getting worse and worse as things get more advanced. Magic can of course change this, but if you don't have that, or any knowledge of how to develop it, escape is a crapshoot. Maybe you'll shift to another reality, maybe you'll shift to another body forward in time like "normal", etc, you don't really know. Nor would you know if it would be better or worse. So unless your situation is incredibly bad it's probably not a good idea.
I have used suicide in a few situations in "the past" but from what I remember none of these cases allowed me to outright escape the world/reality/dimension I was in at the time. The main case was being stranded in a frozen tundra with a broken leg, a few other injuries, and no supplies. Me and the other person I was with had no real choice but to inject ourselves into the local soul cycle or whatever you wanna call it and live out a bunch of lives until things got advanced enough in the societies we were in that we could both remember everything and redevelop enough magic to leave. Took a really long time and wasn't all that fun from what I remember. Kinda one of the bigger inspirations for why I wanted to get magic so bad in this life.
