What is most likely the reason this engraving by paul revere of the boston massacre inflamed public opinion against the british?

The engraving done by Paul Revere represented the Boston Massacre. This was when four unarmed colonists were killed by members of the British army. This incident happened shortly after a series of taxes were put on the American colonists.

Paul Revere depicted this event in an engraving that shows the American colonists as being brutally murdered by the British army. In the engraving, all the British military members have guns while the colonists are standing their defenseless. This inflamed public opinion because it showed the British army as monsters who killed colonists without a cause.
