Punching Irvine into the face wasn't exactly nice either. Even if you don't like Irvine and even if Senna had every right to be annoyed at him, this does not justify the use of physical violence. Come on, talking to him like "Hey, I am Senna the God and you are a newbie so stay away from me on the track" - how arrogant is that? Senna even threatened Irvine he would use his influence on the FIA to get Irvine out. With all due respect to Senna, this is very much prima donna like.
Legally his move on Prost is worse than what MS did in Jerez. If JV had been killed they could have convicted MS for manslaughter or rather
bodily harm with fatal consequences since his move on JV was spontanous. They could never prove that he had planned to take out JV before the race.
If Prost had died Senna could have been charged with murder since what he did was planned. It would even have been a very severe case of murder since "revenge" is considered a "base motive" and usually does not allow an act of grace.
