No, the GPL only allows to distribute software when the sourcecode is available. When Jerry releases it without source, he is violating Tom's copyright.
However, when it is really that important, Jerry could convince Tom to license the work to him under a more permissive license.
Should Tom be unwilling to cooperate, then there is another loophole Jerry could exploit: Jerry could see how many people he can save from Something Evil by running the software on his own computers. The GPL only limits distribution, not use of the software. Jerry could even offer other people a way to access his computers remotely so they can use the software via internet (for example by using a remote administration software like VNC or by using a desktop virtualization system like Citrix). As long as the binary code does not leave Jerry's hardware, no distribution has taken place. If Tom would have wanted to avoid that too, he should have licensed his software under the AGPL.
