suffering and ~intentional suffering. Ex: when you decide to conceive a child, you voluntarily embark upon a mix of joy + suffering - about which you cannot even remotely guess .. what's next. But you know that for ~18 years minimum: you shall be Responsible.
The suffering of a traffic accident (especially a solo one not involving the sudden breaking of the frame in 3 pieces?) .. is never an intentional event. Not even a particularly good example, that. Here a deranged view of 'causality' rears it's ugly head - deranged because it is insoluble in this context - except for lunatics, forensics and lawyer-type punctilious mindsets.
The troops in WW-II, at least some of those: had an idea of what was worth the risk of dying-for. It is from this *kind* of voluntary suffering that we get the Beethovens ;-) and from a succession of 'the daily accidents' we often get the serial killers (who never noticed that their own actions created their finally deranging.. accumulation of 'sufferings').
