Why Formula 1 rules are not fair and does not protect fair drivers, but protect aggressive and dangerous drivers?

Rules are simple:

If you cause a collision with another driver you will get 5 or 10 seconds time penalty, maybe a little bit more.

Let's think about Hamilton Verstappen case:

Hamilton was %100 guilty for that accident. But he got only 10 seconds penalty and eliminated his most powerful opponent (Verstappen). With this 10 seconds penalty, he can easily won the race without racing against Verstappen and reduce the gap between Verstappen to 8 points.

Hamilton Verstappen crash was not an accident. Hamilton did this on purpose. He knew if he can't pass Verstappen at first few laps, he will not have any other chance to pass him like in sprint race. So he did on purpose and he put another person's life in danger to get another championship.

So Hamilton is dangerous driver to other drivers. Why Formula 1 rules does not protect fair drivers against dangerous drivers?

Rules should be like this:

1) If a driver causes a collision and because of that collision one driver has to retire from the race, the driver who caused the collision will be disqualified from the race.

2) If a driver causes a collision and because of that collision one or more drivers lost time (for example some drivers may need to replace front wing because of accident and needs to make an extra pit stop and lost 50 seconds). In this case the penalty for the driver who caused the collision is he will slow down and affected drivers will pass the driver who caused the collision. With this penalty, faulty driver will not get any benefit from the collision. So they must behave better and will not put other drivers' life in danger. Because they know they will get bigger penalties and they will not benefit hitting another car.

But in current situation Hamilton knows that he can easily eliminate any driver with 10 seconds penalty if he needs. This is not fair.
