In the original airings of "Just One Bite" Squidward is seen trying to break into the Krusty Krab, and is doused in gas he is set on fire twice. Subsequent airings edit it to Squidward already approaching the Patty vault. The main reason this was edited out is due to the 9/11 terrorist attacks and the aftermath.
Stupid, idiot, barnacle-head, barnacles, kill, fish paste, tartar sauce, shrimp, and moron are frequently used. Darn, heck, butt are infrequently used.
In later seasons, the word chum becomes a euphemism for the "s" word.
In "Sailor Mouth," it is implied that SpongeBob and Patrick learnt "bad word #11" and started using it everywhere, even though it was all censored but it is never confirmed what the word is as it is covered up with dolphin noises. On the trashcan it says "Krabs is a...," and SpongeBob mentions the hidden bad word, though it was censored and we don't know which one it was. The moral of the episode advises against swearing.
In "Krusty Love" SpongeBob's patience is tested and he ends up saying alot of unintelligible gibberish, this is meant to be an equivalent of swearing. Even Mrs. Puff is seen thumbing through a dictionary and blushing.

The "Nasty Patty" is a pretty dark episode, but it's mostly because of dark humor.
The controversial episode One Coarse Meal involves Mr. Krabs driving Plankton to suicide. Although this should be handled seriously, it is instead handled in a comedic manner, and Mr. Krabs is rewarded for his actions, which will upset many viewers.
The episode "Demolition Doofus" may upset some because of Mrs. Puff's unusual sociopath behavior.
"Bossy Boots" has a scene where Pearl and SpongeBob try to come up with a new name for The Krusty Krab. SpongeBob comes up with "The Kreepy Krab" which depicts him as a mad scientist holding a mutated crab. He then comes up with "The Killer Krab" which shows him with a rather barbaric appearance.
The episode "Gary Takes a Bath" has a scene were a face of a girl with pigtails smiling pops up almost like a jumpscare, this may be frightening to some.

The original version of "Shanghaied" that was shown in theaters before a movie, has Squidward thrown into a demonic atmosphere known as "the fly of despair", originally skulls and skeleton remains were seen when Squidward was falling through.
