Either way, what he is especially: arrogant.
He is arrogant enough and considers his opinion important enough to determine when a forum can be deleted, i.e. he thinks he knows best what others should be able to discuss.
Even if there is not "the cure" on the horizon, people still want to discuss research. Deadman1's mental horizon, unfortunately, does not seem to go far enough to see that. He just declares this forum can be deleted because he thinks he is the authority to decide when an issue needs no longer be discussed.
