Not a question of language error, I'm just interested in how different parts of the world have different takes on when taking a life can be legally justified. FWIW, in your scenario, if I simply shot the man and killed him, then I would fully expect to be questioned and possibly charged, and only acquitted if I could demonstrate killing him was a justifiable act of self-defense. I don't imagine whether he'd broken the door lock would be considered particularly relevant. As it happens, I've forced locked doors open with no criminal intent - I'd simply lost my key and needed to get back inside my own house. It's not impossible the man in question had got confused about which house was his and was doing the same thing.

I got it. If a man breaks into your house, begins walking up the stairs while your wife and kids are there, you're going to be cautious to see if stopping him with deadly force is necessary. Maybe first let him strike you in the face too. You wouldn't want to kill him if he's punch only knocks you down and allows you to get up and fight him off like a super hero! And if he punches you so hard you loose consciousness, what's the worst he's going to do? Rape your wife?

Yes, I absolutely would be cautious - if nothing else, attempting to stop him with deadly force may well be what triggers the situation to become violent and life-threatening for my family and myself. But more importantly, all the circumstances I can realistically imagine myself trespassing into somebody's house do not involve me intending any harm to any of the occupants, so I would very much hope most people would approach such scenarios with similar caution.
