The devil knew I had a moral compass. So he didn’t present it as a moral issue. More like an experiment, or a problem to be solved. I didn’t hate my brother or want to hurt him.
What’s scary is how many teens today don’t have a Christian moral compass and still are vulnerable to temptations like this. I can well see this could be a problem to latchkey kids when one is much older than the other and expected to be in charge until Mom or Dad gets home.
