The distinction between me and the indifferent Universe in which I exist is quite simply this:
The Universe is indifferent to the suffering of others by its nature. The Universe quite frankly has no choice in the matter, for the Universe by its nature, lacks the capacity to care about anyone or anything.
I, on the other hand, have a choice in the matter.
Hence, when I am indifferent to the suffering of others, my indifference and lack of sensitivity is a matter of personal choice.
The choice as to whether to care or not is mine to make.
If I am indifferent to the suffering of others, and insensitive to their plight, I have no one to blame but myself.
