It's not inevitable. Would you describe Brendan Cox's response to his wife being murdered as hate? Here are some quotes:

"We are not here to plead for retribution. We have no interest in the perpetrator. We feel nothing but pity for him, that his life was so devoid of love that his only way of finding meaning was to attack a defenceless woman who represented the best of our country in an act of supreme cowardice. Cowardice that has continued throughout this trial."

"All their lives they have been enveloped in her love, excited by her energy and inspired by her example. We try now not to focus on how unlucky we were to have her taken from us, but how lucky we were to have her in our lives for so long.”

"She would have wanted two things above all else to happen now, one that our precious children are bathed in love and two, that we all unite to fight against the hatred that killed her. Hate doesn't have a creed, race or religion, it is poisonous.

This picture is aimed at people like Thomas Mair whose hatred led him to murder an innocent women.
