There is no useful world's-most-dangerous answer without a definition and evidence. Conditions and preparation can change the risk on any route.
Ask what creates the hazard
Look for exposed sections, water crossings, unstable ground, difficult navigation and limited exits. Ask whether the description applies to the current season. Popularity and dramatic videos are not safety assessments.
Compare the route with your experience
Describe the terrain you have actually managed, not just your fitness. Equipment is useful only when appropriate and used competently. Avoid treating a notorious trail as a challenge you must complete to become a serious hiker.
Choose a suitable Atlas objective
Ask Atlas Hikes for a route matching your abilities and current conditions. Read the Toubkal difficulty guide. A worthwhile holiday does not need danger as its selling point.
