I look it this way. People seem to be very different to what they need to experience different feelings. To put that into one-dimensional scale (which does not give justice to the wide variety of peoples' feelings but simplifies the analysis):
One may sense tremendeous joy seeing new flowers in the spring and vast sense of disappointment missing a train when next leaves 15 minutes later.
In order to get the same sensations, some other needs to success in something in which a failure would mean death, or fail in something very difficult that he/she has been working on years.
Now, if you force the first person to not have those sensations, what will happen? I find it a very possible outcome that the life becomes so unbearable that the person is ready to kill him/herself. If this is remotely correct, it should be quite easy to see why some people are ready to take fatal risks voluntarily. To feel something.
