He may not have been the best character but he lost his son cuz Mary wanted to be Stubborn and a 'good queen' costing even more lives than the one his son was asking for and rightly upset over her purposely infecting him with Plague and later giving her hell for it. Now he's not only lost his son, but later the new love of his life, again, cuz of Mary (though the letter was forged, her loyalty to her got her killed) and Lola lost her future (Francis inisting she stay at court and publicaly annouce his bastard) and later life staying by her. Who DIDN'T suffer staying by her?
Don't get sad she was a pure b*** in the whole series and betrayed the owner who fed her supported her ,and even slept with her friend aka owner's husband.
