Why is it that on Internet forums, such as Facebook and Reddit, and the knee-jerk reaction of many people is name-calling and statements judging the value of a person's life.
Have you met any of the people involved or any of their family members? Do you have evidence to support your statement that they are "pathetic" and deserving of "uncurable forms of cancer"?
We should all remember that we are all imperfect human beings. You can judge the actions of a human being to be or not to be "right" or "wrong", but it's not appropriate to judge the person themselves, especially when you've never even met them.
