I read the article, and I'm sorry, I do not think you know the meaning of the word "cause". He did not cause any outbreak.
Not providing help is not going to cause anyone to suffer. What causes people to suffer are other factors (for HIV, it's usually unprotected sex, careless intermingling of blood, etc). Refusing assistance doesn't cause people to die. The disease kills them.
Now if you make a case that Pence was directly involved in infecting them, then yes, he caused it.
Assistance is exactly what it is: It is help. My refusing to help someone does not mean I caused his misery. Nor is it punishment, another word often used in these situations.
While I disagree with Pence's actions, I can also point out false allegations made against him.
