Symbolism has polluted people's souls for centuries.
It is true that a certain type of image can refer to a certain meaning, such as the skull to death.
But we are not animals and we are endowed with reason, often instinctive reactions, like those of animals, lead to errors of evaluation.
The image of the skull is neither a warning nor a source of fear, but rather an emphasis on the cycle in which every ending carries the promise of a new beginning.
