Tapper's actions were not Judas-like at all. Judas did what he did for 30 pieces of silver and he betrayed Jesus on the sly.
Tapper's actions were blatant [drastically so] and it's highly possible I know more about his motivations for his explosion than he does. But to put forward those opinions [which were explained to me by others post-event] would be inappropriate for the public [or even for the private] domain I guess. To make such a discussion appropriate would require at the very least, informing him of such a public discussion....and potentially even his consent. To simply inform him would potentially be malicious - and he would never give his consent.
