All-In-One
From the perspective of a Jew who knows that his purpose in the world is to serve his Creator, this means that the internet is also a tool to provide access to ever type of vice to which a human may stoop. The internet provides an opening for each person to fall prey to his unique weaknesses.
Another person has a hot temper and is constantly getting into fights and disagreements with others. Words fly bitterly and it is only by a miracle that the fists do not join in. Now that person is introduced to the Word Wide Web. Instead of sleeping on the matter and cooling down by the following day, they can act immediately by sharing their anger with millions of others instantaneously. The flames of machlokes can be fanned like never before.
Because it is always accessible, 24/7, a person need not be entirely dissolute to be trapped. You can stand strong day after day and resist the temptation to sin. The internet is patient and will wait quietly to manipulate you in your moment of weakness.
Whereas in the past, weak individuals sinned in private, today they drag others along with them. The internet has raised the science of temptation to all new heights.
