I think that people in general are decent and good. There are always some bad apples, but during crises most people want to help others. During the coronavirus pandemic, many people are doing everything they can to help others, including assisting neighbors, family members, friends and health care workers. Charitable organizations have stepped up to assist those in need during the crisis as well. Generous people donate to charitable organizations to assist in their efforts. This is where the bad apples come in.
Bad apples know that most people are decent and good. They know people want to help others, and that people are generous and kind. And the bad apples take advantage of the goodness of others. During a crisis, like the one we are in now, bad apples spend every day trying to figure out how to do just that.
