Gaining a skill that might cause serious problems in the future is actually a great way to keep the story interesting. Especially since, time and time again, in stories where you gain more and more abilities, it can get stale quick. We've already seen Yuuto have issues controlling himself when one of his classmates died, it would make sense that this will build into a future chapter when he's unable to protect everyone. It's a shame that this comment has so many likes, it's very immature to read.
As others mentioned, it
could be a good way to keep the story interesting... if it fit the story.
Maybe in a future point, when he is fighting people that could be an issue for him, having it as a drawback to be wary of could be interesting.
Or if it was activated the more of his power he used instead of the more in trouble he is, since as you pointed out in stories where people get more and more power they just throw it around like peanuts.
By this point, the MC barely struggled until now. He has lots of power now, but he barely ever used it. And, as others complained, he is more of a follower than a doer.
So, right now, Berserker is kinda nothing. And if it is ever called back on in the future, since it would have been so long since it even entered anyone's minds and, with the rhythm it is going, no one would even bother remembering it by the time it could be relevant... "remember that skill he absorbed dozens of chapters ago and never did anything since then?"
Yeah. Would have been much better if it had been added
then.
