I loved him (peace be upon him) because it was like he had the characteristics of all the previous prophets in one final human form.
Some prophets were strict i.e. Musa, and Nuh (peace be upon them) because they wished destruction for their nations [obviously because their people rejected islam.] And some prophets were too kind, like Ibraheem and 'Eesa (peace be upon them) because they stayed patient, and left the peoples fate upto Allaah Almighty.
However, Muhammad (sal Allaahu alayhi waSalam) had the characteristics of all the good qualities of the previos prophets - so he was in between - the middle path.
So it makes you feel happy that we can follow that example, and follow the middle path. Therefore, if someone tells us that we're being extreme - we can tell that we have the right to defend ourselves, and if someone is kind to us wholeheartedly - we can show mercy to them too insha'Allaah.
The Last Prophet's (Peace be upon him) calm, helpful and kind personality and his teachings which are still heeded today by many Muslims around the world and Insha'Allah they will still be heeded in the upcoming future also his unique act of forgiveness for anyone.
