At the same time, though, it's typically the jungler that gets this hate from his team. I play a lot of jungle myself, and typically if someone overcommits to a fight and I'm somewhat nearby, they will spam ping me even if it was a 1v5 or i had literally 1 HP. The jungle is a highly strategic role - probably the most strategy in the game. You're typically trying to be your team's shotcaller, babysit everybody, make the right objective calls, give buffs, gank lanes, get farm for yourself, and, if the enemy jungler has ganked a lane twice in 5 minutes and the laner died both times, even if you were on the opposite side of the map when it happened, it's somehow your fault for not counterganking. You're getting tired of being blamed for the jungler's mistakes, and the junglers are getting tired of being blamed for their laners' mistakes. It happens. It's not cool, but it happens. There's not really much of anything you can do about it. They probably only read you the riot act when they mess up and you don't do anything about it because they expect you to do the same thing to them. I play both the jungle and the lanes, and I have been there, done that on both of these. It's been a while, but I have. And I'm pretty sure everyone has. It's all a part of the mindset. Just know that, while they're spam pinging ?'s at you for not saving them, they're not looking at their mistake and they aren't improving. Meanwhile, you're improving by recognizing that you can't do anything.
Also, I've turned situations that really shouldn't have turned out well for us because one of my allies showed up, and it really shouldn't have been good even with them showing up, and won. Learning to recognize situations when you can and can't help is good, but you at least moving in that direction and trying something if you know you can do it safely will at least keep them from being babies too much. Move, even if you won't get there in time, so that way they can't complain because you at least tried. It'll help them to not tilt and possibly even prevent them from trolling/inting. There's a lot of babysitting in League, and this is part of it. I'm not saying they're right to complain at you or that you did anything wrong by not helping them - you recognized that they were dead either way and you probably wouldn't get anything out of it - but having a teammate troll/int/afk/tilt is worse than you missing a few farm.
