One person did not lose the game for you, the person who fed if they even fed most likely didnt get help just sat there as you called them bad. its a team game not a free for all. help your teammates instead of blaming them cause youre mad you lost
The tricky part becomes what qualifies as 'helping'. After a lane gives up a few kills to their lane opponent, trying to roam and gank that lane is just as likely to give them a double kill as it is to shut them down, and meanwhile the roaming lane is going to be pushed (or their lane opponent will roam too), potentially setting another lane behind.
Raging at someone for feeding never helps, but sometimes the best thing you can do to help them is to focus on winning your own lane so you can be useful in carrying them late game, and just hope that the person having a bad game has the sense to stay well back under their turret.

This I see every match. Even when you get in higher elo you still see it. Its sad.
Its surprising how many people activly tilt themselves while blaming others. Just chill and play. Its not that hard.
