I don't think he deserves that much hate. Don't get me wrong now, he's far from being the best guy but he's not nearly as terrible as you guys say he is (from what we know about him as of now).
He can be hot headed (under the influence or maybe not) but you can reason with him and shake hands (with enough charisma)
He could either be protective or a show off to impress girls but I'm 100% sure that he's the kind to fight for his girl.
He is also paradoxically, patient and impatient. He's been trying to get Lena's attention for as long as she worked at Yunalesca but then rush things out when he finally gets a date with her.
From what we can see, he seems clumsy during sex ... who knows maybe he doesn't have much experience and maybe his whole behavior is an act to hide that and he's actually self conscious about himself (I doubt that anyway)
These are my opinions, not facts btw. Don't nuke me for thinking outside the box
