Minecraft wiki entry for Things_not_to_do, associated text: Do not attack zombified piglins without ample preparation for the consequences. For example, the player should be in an advantageous position or must only be near a few zombified piglins to fight them. Like wolves, nearby zombified piglins all become aggressive to the player if one is attacked. Zombified piglins hit harder and are faster than regular Zombies, so it is better to kill single, isolated zombified piglins unless the player is well-equipped and experienced enough to take on large groups. A building defensible against zombified piglins with holes for visibility is advisable. The player can knock them into lava as a defense method because lava slows them down and gives the player time to escape, but the player should remember that all Nether mobs, except piglins, piglin brutes, and hoglins, are immune to fire and lava. If the player is quick enough, they can pillar up a couple of blocks and attack the zombified piglins safely from the pillar. If the player wants to kill zombified piglins without angering them, powering TNT with a button does not anger them as it counts as environmental damage, and killing them in one hit does not either. This can be done using a Smite IV or higher diamond or netherite sword or axe and performing a critical hit, or using a potion of Strength.
