It’s not uncommon for players to have a plan in mind on how they want to spend their skill points. Luckily, this doesn’t affect companions, but it makes the perk feel more inconvenient when you have to make sure nobody is watching, especially if you’re desperate for health.

The main problem with this perk (besides how gross it is) is that if someone sees the player eating a corpse, they’ll turn hostile and start fighting the player. The Cannibal perk lets players eat any human and non-feral ghoul corpses while they’re sneaking so they can gain HP. Cannibal is sometimes a good perk for players who want to have negative karma, but even then, it’s not that great.
