Depends on the law.
In other countries hitting someone in a vehicle is considered assault regardless of the circumstances and is enforced as such.
I would condemn the driver, the one with the responsibility to drive a tonne of steel around safely, over the pedestrian being an nucence(?) on the road.
If the law is the other way around. The law needs to be changed.
Everytime I see suicide statistics like these. I don't think of the deaths. I think of the misery each individual must have experienced in order to come to the conclusion that death was better.
Then I think about the nebulous political cloud surrounding these people and those who may have approached the conclusion but had the strength to carry on. I say nebulous because research is never going to encapsulate the reasons for one to kill oneself. If 50k in the US is the number who followed through, the numbers must be huge. I say this, because the suicide death statistic, is only the start of the problem - it's a scale.
Misery festers at all of us. Labels, drugs and conversation can help, but it's just burying the problem for it to resurface later. Until we start getting political movements towards human needs, this will continue.
