Idk about where you live, but “versuchter Totschlag” is very much a thing in Germany. Translates to attempted manslaughter and is in essence an extension to aggravated assault for cases where it should be obvious to the perpetrator, that their actions are significantly likely to cause death.
Specifically kicking the head of a person who is already on the ground is one of the things that is basically guaranteed to get you charged with that .
Don’t worry, I did the same. Just assuming that legislature would be the same and all…
