Here; I can prove that a Christianity teaches a lack empathy, and breeds self-centeredness, with simple algrebra.
Christian's thought process: "athough I am eating alone tonight" comma "many children will die of starvation tonight" therefore "I am blessed!"
Now, let's look at it at an non/empathetic manner; by definition; the focus of thought on which set of beings; ie; "I am" = 1 and "many" by variable "N"
1 + N = 1
-1       -1
      N = 0
Thus, Christian thought is a selfish lack of though for others.
