Most psychiatrists would agree that one is unable to love another, or in fact the human race until one truly loves and accepts themselves. Therefore if one feels such deep “hatred” for another, they must know in their hearts that they are in fact wrong. This has nothing to do with religion, but simply morality. External excuses such as ‘religion’, rules and beliefs are only forms of self deception and false rationalisation for this hatred. However not many people are able to accept this and instead fuel their hatred upon others out of denial. I think this would apply to many people who associate themselves with groups who enforce terror upon others, be it the armed military, playground bullies, terrorists, radical sects, criminals etc. I don’t fully agree with the picture below because I don’t condone suicide or violence but there’s a slight truth in it which is both horrible but just.
