Of course any deaths are extremely sad and thoughts go to those left behind.

Unfortunately the corollary to these events is that it becomes far more likely that the rest of us will see further restrictions and regulations imposed on us in order to try to reduce these statistics.
As said by others there will always be the true "accident" where something unpredictable happens, but so often the primary factor is the deliberate actions of the rider, whether excessive speed, unwise overtakes, or simply running out of skill.
Sadly so many folk seem to have no sense of "what if ...".

My adage for riding bikes on public roads is "if in doubt, don't". It's kept me alive for a long time now.
