I have not closely followed this case, but wanted to explain why the prosecution may have introduced evidence of Rittenhouse's retreat and Rosenbaum's pursuit, etc. Actually, there are two reasons.
1. Idealistically, prosecutors are "ministers of justice" who, IMO, have the responsibility to present uncontradicted evidence of what really happened when that evidence exists. We can look back at the extreme example of what can happen to a prosecutor who ignores this responsibility in the case of the wrongful prosecution of the Duke lacross students. Although, that case did not go to trial, the principle is the same.
2. More practically, it is almost always better for the prosecution (or the plaintiff in a civil case) to present "bad" evidence in their case, rather than letting the defense present it in their case. The thought is, first, the prosecution is fair, thus building credibility with the jury. Second, it keeps the defense from "scoring points" with the jury. That doesn't mean the prosecution puts on the defense's case.
