In The Bronze Bow by Elizabeth George Speare, why does Daniel walk away from Jesus at the beach?

In
Chapter 5, Daniel travels to Capernaum,
where he sees a crowd gathering near the harbor. Daniel
walks towards the
harbor, where a woman feeds him and tells him that people are gathering to

hear the teacher. Daniel then turns toward the man who is preaching and listens as Jesus
speaks
about the kingdom of heaven. Daniel is enthralled with Jesus' presence
and speaking abilities,
until he is distracted by the clinking of metal. When
Daniel turns around, he sees two Roman
soldiers standing in the crowd. Daniel
is disgusted at the sight of the soldiers and immediately
spits at the
ground. Despite the soldier's presence, Jesus continues to preach as Daniel
becomes
increasingly angry. Outraged, Daniel turns around and leaves the
crowd. Daniel's
hate and bitterness towards the Roman soldiers
make him leave Jesus' sermon. He is also upset
that Jesus did not ridicule
the soldiers and allowed them to listen to him as he preached.
