You make a great point here, @Basil! When I first when to South Korea, it was shocking to see the swastika symbol proudly displayed on walls and temples. But it turns out to be exactly what you said- this symbol was originally a symbol of peace and well-being before being stolen, twisted, and given a much darker conotation by the Nazis.
There’s a great article in the BBC for anyone interested: How the World Loved the Swatsika- Until Hitler Stole It
When it comes to things like symbols (especially with very emotionally and culturally charged symbols)- it can be important to consider their historical ties, culutral significance, and personal meanings in order to read their energy 
It can be the same with numbers too! I always think of the number 13- while it is my personal lucky number, many see the number 13 as a number of bad luck (think Friday the 13th 
!). Or how the number 4 is a normal number in many Western cultures, but is associated with death in parts of Asia 
It is fascinating to see how numbers and symbols can carry different interpretations and deeper meanings to a person based on their own culture and experiences
