I hate when people try to profit off others misfortune

I can think of way worse incidents of exploiting the misfortunes of others than someone buying several tickets, where the money goes to relief funds, to a concert and selling them to people who want to go. Is it a classy move? No, but on my list of things to get mad at, this is way down there. If they sold fake concert tickets, or price gouged a necessity during the tragedy, then ok.
