The above verses are confusing.why would anyone want to kill another for having a difference of opinion?
There is nothing confusing whatsoever.
Most verses that kuffar cite
always , without fail, involve the pronouns they or you.
Unless you know
specifically who
they or
you refers to, you would not understand the passage.
Therefore, in order to understand the passage you would need to read the context.
Nothing too discomforting in there.
