it could be that following the scripture leads to death, something you do not acknowledge... which is fine, if you want to deny the obvious then go for it, doesn't mean you are honest though.Ha, seriously the verse said honor so you can live a long time, didn't account for a parents conduct.
Where in the verse does it say "under these conditions honor"?
you got half a brain use it.
here read it, it doesn't matter the instruction for the parent in the context of the verse
Exodus 20:12 - Honour thy father and thy mother: that thy days may be long upon the land which the LORD thy God giveth thee.
so what if parents have rules to follow, that isn't the point of the verse.
the verse stands upon it's own merits, your verse choice Colossians 3:21 doesn't change Exodus 20:12 which can get a child killed.
The best thing you could say to stay true to the verse is "the child was supposed to die, God's will/mystery occurred"
Wow. I mean, I don't know what kind of experiences you may have witnessed in your world, but the verse you give is pretty much the way to go when it comes to parents and their children. For the good of the children. That isn't a theist exclusive principle, it's a human one.
