Sure, there are sane guardrails in place. Your are not allowed to shoot at somebody who steals a bottle of water from you or makes a picture of you against your will. You also correctly mentioned kids or sick people that do not have a criminal intend in a narrow sense.
Generally however, you don't have to flee and the defence doesn't need to be proportionate to the attack or what you are defending.
You just generally have to choose the mildest defence available to you that you can reasonably know having under an ongoing or imminent attack - you don't have to "take your time and look around" if some milder defence is around the corner.
