in any situation the root of it all is either fear or love, those are the only two motivations that exist. think about any interaction that comes up, and ask yourself WHY, in order to go a layer deeper, and you will build a mental tree, starting from the leaf and think down, and you will find the answer at the root. FORGIVE those people who act on fear, and be patient with them and time itself will correct their path and show them the truth.
through thought, you will arrive at a point where you understand the motivations of every being, and from there you will achieve inner peace
comment if you want your examples worked through to show how this works
