And if that little boy maliciously threw a rock through a window? Would you still hold him in such high regard even after he received a smack on the hand from his mom?
And an offside goal is only worse in your opinion! In mine it is something that is missed by the assistant, and merely human error. In this instance everyone knows what happened but there was no punishment to suit the crime!
Same logic could be applie to criminals... A murderer kills people for fun - to satisfy their own needs, yet his punishment is jail for 20 years... is that a suitable punishment? That sounds to me like holiday for the next 20 years, free food, accomandation.
In this instance the punishment is Red card, banned for next match and Penalty to the opposing team. Penalties are generally regarded as a freebie goal in Football... why do you think the world and it's mother of all supporters cheer when their team is awarded a penalty?
