What people generally see in the cross of Christ (suffering, pain, death)is all absolutely true, but there is a deeper level of truth here. The deeper truth is that on the Cross, Christ dealt a decisive blow to Satan and sin. He "Disarmed the rulers and authorities and disgraced them publicly." The Via Dolorosa, when viewed this way, is actually a victory parade...and that is actually a word Paul uses here in verse 15 a "triumph" which was a Roman victory march back in Rome.
