Is it permissible to watch websites and Bluetooth clips that attack and curse the Companions, knowing that I sent them to some of my friends to show their malice?

Watching websites that attack and curse the Companions for entertainment or promotion is forbidden. However, watching them with the intention of understanding their malice in order to warn against them and refute them, provided there is no risk of promoting them, may be a good deed for which the doer is rewarded for defending the religion.
