That is a bit misleading. If a woman doesn't buckle her child's seat belt she can be charged even if somebody hits her car. In this case she started a violent argument with another person and it resulted in the death of her child.
Also, the article was from years ago. The charges were literally dropped despite an indictment from a grand jury.
As someone coming from a different ethical background I think your comment is complete inline with what would irritates me regarding the case (without considering the legal outcome). Putting an unborn on the same level as a child and to even blame anyone for triggering gun use while being unarmed themselves seems totally outside my reality.
It should be taken into account the article is not from US media. Typically in Europe it would probably not be considered misleading for the aforementioned reasons.
The majority of states in the US considers killing a pregnant woman the same as killing two people (assuming it doesn't happen during an abortion). This is consistent with the existing laws in most states.
Using a gun even if another person is unarmed can be justified. If somebody is trying to kill you, you have a right to defend yourself. If you have a gun then you can use it. If somebody was unarmed, trying to kill you, while you are holding a bat would you find it acceptable to use the bat to defend yourself? If you would defend yourself then a gun is no different. If you would not then we disagree on the concept of self defense and don't think we are going to agree on anything high level when we can't agree on the core principles.
