It is important when reading about the life of Jesus to remember that he lived under the rule of an occupying force whose motives for the occupation were profit from pillage, and profit from exploitation, and profit from trade. There was no respect for (or understanding of) the Jewish religion.
In Taken at the Flood by Robin Waterfield, Republican Rome (i.e. the culture of the 500 years immediately prior to the time of Jesus) is clearly shown as a warrior society. Warfare was one of the principle sources of income for both the country and the generals and soldiers that fought those wars:

“In short, a state of war was not only considered ‘business as usual’ in Rome by the entire population, but was not considered undesirable, especially by Rome’s aristocratic leaders. It is far harder to recover the motives of the ordinary soldier, but several of Plautus’s plays (third/second centuries) suggest that the attraction of warfare for them too was profit. It was bound, then, to be relatively easy for the Romans to go to war; and it was equally easy to present the wars as justified self-defense or protection of weaker neighbors. Slight pretexts could be taken as serious provocation. This is not to say that Rome was the aggressor in every war it fought, but the facts remain: Rome was almost continuously at war in the early and middle Republic (500-150 BCE, in round numbers), every opportunity for war that the Senate offered was accepted by the people of Rome, and the benefits were recognized by all.”
