Minecraft wiki entry for Survival_with_no_enabled_data_packs, associated text: The villagers' worst enemy is you. For a large village, your presence can bring a zombie siege. Even in a smaller village, your presence brings mobs, and these rapidly kill off the villagers. So for your own interests, as well as theirs, you must be sure to be a long way out of the village before nightfall, and not come back until the sun is well up. You need a shelter at least 33 blocks from the village center. Unless you are sure where that is, give a good safety margin and stay 50 blocks or more from the village. This applies to all villages, even ones without a farmer - you may well be back to trade in this village after you have done your initial trades with a Farmer. A deserted village or zombie village is no use to you.
