Acts17apologetics wont die for a just cause like their saints; Martyrdom highest deed in Islam?

In answer to the video "Paul's Revelations Made Him a Better Man; Muhammad's Made Him Worse (PvM 16)"

Choosing to safeguard one's own people from physical and spiritual oppression, putting one's own life on the line to defend the oppressed and advance the cause of truth is the most selfless material and spiritual sacrifice one can do. Every culture and civilization in history has owed its survival in the face of oppression to these types of honored individuals.

But even then, as in any army, there are degrees among soldiers, hence the prophet saying that military participation is ranked 3rd in terms of divine appreciation

"I asked the Prophet 'Which deed is loved most by Allah?" He replied, 'To offer prayers at their early (very first) stated times.' " `Abdullah asked, "What is the next (in goodness)?" The Prophet said, "To be good and dutiful to one's parents," `Abdullah asked, "What is the next (in goodness)?" The Prophet said, "To participate in Jihad for Allah's Cause." `Abdullah added, "The Prophet narrated to me these three things, and if I had asked more, he would have told me more".

However those among the volontaries going to such extent in their selfless sacrifice that they are martyred, the prophetic sayings describe them as meriting the highest reward. Wordly gains certainly follow as a collateral result of wars, and although are certainly the just compensation of those sacrificing their wealth and resources on the way, the Quran stresses that these wordly gains must never be the motive. In a hadith the prophet even answered about someone fighting in God's cause but also seeking material reward, that in the herafter "He would receive no reward" (sunan Abu Dawud).
