The victim in that assault case has been shoving and grabbing students at the university before. That is of course much less severe than how he was beaten up, but in that discussion about throwing out students for violent behaviour that was conveniently ignored.

The whole discussion only started when he was attacked and it was about denying education to pro Palestinian and in particular Arab and other migrant sudents. It was headed among others by the racist major of Berlin (major in this case is also the head of the state government) who just a year ago won an election on the grounds of demanding police to release the names of suspect teenagers. This demand was made so the public could decide based on the names, if those suspects were "real Germans" instead of maybe "foreigners with a German passport". This is far-right nationalist ideology and primitive racism.

So it is clear what goals are aimed at with the demand to throw students out of universities if they are suspect of a crime. If it would be put in place it would be used to remove "foreigners" from universities, not to remove "good kids who have made a mistake".
