In the UK that would possibly (but not definitely) be manslaughter rather than murder – but I applaud the german prosecutors
Normally, you are charge with an offence even if you didn;t mean to commit it, if you knew that the actions you took could potentially have the same result. E.g. if you throw a heavy concrete block off the top of a wall alongside a crowded pavement, you would be charge with GBH as you may reasonably expect that the block may hit a pedestrian and cause injury. You may not intend to cause injury, but the consequences of your actions could be seen, hence you are charge with the offence
The only exception to this is murder, which must show some premeditation. If someone dies as result of an unexpected consequence of your action, it’s considered manslaughter. you do need to consider the action – e,g, “I only punched him, I didn’t expect him to die” is not a valid reason to be considered for manslaughter rather than murder – edit, as jamba also says above
