I will not condemn the liquor store owner. Jesus will do that. Jesus says that people can lead others into other kinds of sins.
“But whoever causes one of these little ones who believe in Me to sin, it would be better for him if a millstone were hung around his neck, and he were drowned in the depth of the sea." (Matthew 18:6).
We know drunkenness is a grievous sin that will cause a person to not inherit the kingdom of God.
1 Corinthians 6:10 says,
"Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God."
There is a woe unto the neighbor who gives their neighbor strong drink.
"Woe unto him that giveth his neighbour drink, that puttest thy bottle to him, and makest him drunken also,..." (Habakkuk 2:15).
