I think the PSA was a little too extreme in its symbolism, even though that was the aim, no doubt, to make these examples as provocative as possible. For that reason, the examples are rather extreme cases of parenting gone awry, so to speak. By the same token, there are so many influences in the world today now more than ever, which can cause someone to stray away from the wholesome upbringing his/her parents put into fruition. Parenting will always be a guide as for someone to live after, but the end result won't always reflect the quality of the parenting.
