Vuu, I don't think you understand the word "deliberate". Which Rossi admitted to (while conceding he ran Marc wide off the race line but...according to him, not meaning to make him crash bla bla.)
Therefore, this 'deliberate' act, during a points scoring race must be handled severely, so as not to compromise the championship, which is scored on points. The other incidents involving Marc, though deserving of suspension for Wilarot, still must factor in as unintentional, that is NOT being done DELIBERATELY. Modern society understands a distinction when assigning charges and penalties. You kill a guy on the road because your dumb ... wasn't paying attention: manslaughter. You kill a guy by deliberately going onto the curb and running over a guy on the sidewalk: murder. You can later say, well, I was just trying to buzz him, just make him run off the sidewalk, I didn't mean my bumper to hit him causing him to hit his head on the fall. If the judge and jury are not insane, they'll convict him of murder. And to be clear, even if you don't manage to kill the victim, the charge is still attempted murder. NOT attempted manslaughter. The sentences for manslaughter and murder are accordingly different too.
Marc torpedoing Wilarot, by riding negligently: suspension.
Rossi deliberately causing a crash during a race: license ban, minimum 6-9 months.
If you live in a glass house, don't throw rocks.
