I think there is nothing wrong with recording the attempt. However, I'm far way too squeamish to visit wpd or bestgore and people there could be mean to the person sometimes. To me the more mangled you become, the less you should consider filming it, but this might be bias because I want to go out by ingesting SN because that is less traumatic than jumping. I often found myself reflecting to ctb vids that I've watched consensually (like 1 hanging vid and 1 SN vid), both gave me some assurance that things will go smoothly. However other kind of ctb footage (blood) ended up traumatizing me. I think you should consider how your video will impact others. Also, don't forget how people could also capitalize on the video or being mean about it. But then again, maybe if you do have a message for someone or even the world, a video is an effective way to convey it, a lot of examples on this one. Though all these don't really matter if you don't care about anything after ctb. If you want to leave a mark, maybe write something or even a suicide note. Personally I also want to stream my ctb, but I don't know how or where to host it and I keep thinking will all my life be boiled down to just a suicide vid?
