@cromat reminds me of this guy that was on the news in my country a while ago. Philanthropist that was doing some charity work in Africa a while ago, killed his ex-girlfriend and turns out he was an abusive piece of shit overall.
You can easily tell the difference between those who care and those who do it for attention by how much they signal their virtue.
True heroes don't boast all the time, they do it out of kindness in their hearts and the gratitude and accomplishment is the reward itself.
True heroes know humility.
