"good" and "bad" are assessments that are not particularly helpful; unless by "good" one means willing to work with us toward mutually beneficial ends.

When we decide some guy or his organization is "beyond the Pale" we mostly serve to limit our own options. The real key is to identify and reconcile key issues rather than people. Some of these guys are never going to get a seat at the table, but that does not mean that a guy they trust from their organization or a related one cannot carry their issues to the table.
