If your adaptation of these stories makes him an unkind jerk you never understood him in the first place.
One thing that so many people get wrong about Holmes is saying that he’s anti-social and bad with people. He’s awkward, of course, in a very classically autistic way, but when it comes down to it, he’s actually pretty good with people a lot of the time. How do we know this? He has a shocking number of acquaintances who are fiercely loyal to him.
There’s Watson, obviously, but then there are the Baker Street Irregulars, who are clearly in it for more than the pay he gives them - they always seem delighted to help him. Across various stories, Watson runs into a number of people who do whatever he wants as soon as he so much as mentions Holmes’ name. Many of their cases could only be solved because Holmes has a network of convenient people who will do basically anything for him. We don’t know what Holmes did to earn such loyalty, but we can guess - he helped them. He was kind to them. We know that he is often much kinder to the outcasts and downtrodden of society than anyone expects him to be, because we see it in his behavior.
I think that this really ties in so neatly with Holmes being both autistic and queer (however you choose to read his queerness). He doesn’t care about the rules of “polite” society, so he often insults people who consider themselves his superiors. But he is always kind to those who aren’t used to receiving kindness from the world, because he knows what that feels like. That’s why the Irregulars love working for him - he makes them feel important! Honorable! Invaluable to his heroic work! He treats them with respect that no one else in the world gives them, and it’s not just because he’s trying to get something out of them. He actually respects them.
And above all, we know that he isn’t antisocial or bad with people, because Watson loves him so much. Watson, who is by all means a much more well-adjusted member of society, is more loyal to this weird little man than he is to his own country, which he literally got shot fighting for. Because Holmes has earned his love and loyalty. Because he’s a good person. And even if he’s bad at the official rules of polite society, he’s good at being kind. And that’s what really matters.
