"The fact that a person acted pursuant to order of his government or of a superior does not relieve him from responsibility under international law, provided a moral choice was in fact possible to him." - Principle IV of the Nuremberg Principles
Saw an adder snake today too, got a bit too close to a bush and there he was coiled up about 60cm in front of me, he left pretty sharpish and so did i lol. There are only two types of snake here, grass snakes and adders, grass snakes are harmless but adders are venomous. though not aggressive unless threatened.
