The conclusion can be mitigated by pointing out the importance of cooperation between different value systems.[31] There are good consequentialist reasons why one should be cooperative towards other value systems and it is particularly important to avoid doing something harmful to other value systems.[32] The destruction of the world would strongly violate many other value systems and endorsing it would therefore be uncooperative. Since there are many ways to reduce suffering which do not infringe on other value systems, it makes sense for negative utilitarians to focus on these options. In an extended interpretation of negative utilitarianism, cooperation with other value systems is considered and the conclusion is that it is better to reduce suffering without violating other value systems.[33]
