I imagine it would be much like portraying a villain in a film or a play, and encounters could be quite cathartic! As always, check with your DM. (Some DMs won’t allow evil PCs in gameplay.) Based on research, here are three of the best evil classes to play when choosing to play an evil character.
3. Cleric
I have always played clerics with good alignments, but there is no reason why a player would not play one that happens to have an evil alignment. There could be benefits to having an evil cleric around in a party. Based on research, it would be more advisable to have a lawful or neutral evil cleric than a chaotic evil one, but that is ultimately up to the player and the DM. Read on to find out why clerics would make among the best classes in a game!
Why Cleric is Great for Playing Evil
All creatures and players, good, neutral, and evil, can be harmed in encounters. Therefore, they will need healing after a battle. Regardless of alignment, clerics can use healing spells, probably except for holy water, but that is up to the DM’s discretion. (Fortunately, 5e is so much more flexible than the first edition!)
Evil clerics may be beneficial to take to an undead location. Rather than turning, evil clerics have the option of aweing and commanding undead.

2. Rogue
A Rogue is a lot of fun to play. Rogues are trained to do what is morally considered in good alignments as corrupt: deceiving, killing, and pilfering. An evil Rogue is not a far stretch, and the PC can have a lot of fun with an over-the-top Rogue. Read on to find out more about sneaking around and playing an evil rogue in your next adventure!
Why Rogue is Great for Playing Evil
Rogues are needed in a party to detect traps, unlock poisonous locks of treasure, sneak around to detect oncoming danger, and to stealthily assassinate the creature that is posing the most threat and causing the most damage! The advantage of an evil Rogue is that they don’t have any moral qualms. They just do it without hesitation.
Assassins are most likely the best subtype of this class. At third level, assassins receive both a disguise kit and a poisoner’s kit. According to the D&D Player’s Handbook, “stealth, poison, and disguise help you eliminate your foes with deadly efficacy.” That kind of goes along with evil.

1.Warlock
According to the D&D Player’s Handbook, “Drawing on the ancient knowledge of beings such as fey nobles, demons, devils, hags, and alien entities of the Far Realm, warlocks piece together arcane secrets to bolster their own power.” Since Warlocks gain their knowledge by making pacts with otherworldly beings, it would be natural for Warlocks to be evil in alignment. Read on to find out why Warlocks are a great class to play an evil PC!
Why Warlock is Great for Playing Evil
Warlocks make pacts, so instead of fighting evil monsters, Warlocks may be able to control them through their pacts with deities.
Much like Clerics, Warlocks that made the Undying Pact would be able to control the undead and are not easily harmed by undead creatures. Warlocks would also have an advantage against disease.
