No, but it is more a matter of degree. Doing something "unwise" may be either ill-advised or done against one's better judgment. To rise to the level of "foolish" requires that it be senseless, or perverse, or completely pointless, or heedless of advice and the possible consequences.
Examples:
"It was unwise to try to cage the alligator without our equipment, but we were running out of daylight."
"Running against the popular incumbent may have been unwise, but it was not completely futile."
"It was foolish to lie to the police when they already had video evidence."
"He took a foolish risk and was fortunate that it did not end in his death."

Odysseus' men were wild, foolish beasts who fell for lots of tricks on their journey, (just like the suitors) and didn't get what the sought so hard to get.. they didn't get home. They tried and failed. Just like the suitors.
