Maybe everything is. You say that holding a door for someone or giving money to a homeless person has no personal benefit for "you", but even these things are seen as transactional because a person holding a door or giving money does expect it to be paid back somehow by someone when they need it one day. They hope that their good deeds will be remembered by society.
teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
