According to today's wisdom, no. Today's wisdom says, "Protect the children at all costs; do not allow themselves to put themselves in danger." The Friar knew that Romeo and Juliet were young and immature. Today's wisdom says that they should be protected by their parents in case they do something which might harm them, so the wise thing would be to tell their parents so they could be locked up.
But perhaps there today's accepted wisdom may not be accurate. Perhaps people should be allowed to live dangerously if they fulfill themselves in the process. Romeo and Juliet did not have long lives, but they were filled with the joy of mutual love. And, as the friar foresaw, by living and dying for their love, they reconciled their families. Sometimes great social good can come from personal tragedy. There may be wisdom in that.
