Im sorry for late reply.
Don't forget, even with everyone fighting in the previous timeline, everyone died in the battle and he only barely escaped because Tina sacrificed herself for him. Would they have fared better if he had told them? Probably, but if 20 people is raised to 100 people, it still won't be enough to deal with 2000.
[Did you see last chapter? MC and Dad is the only one fighter at village. Not everyone. They are just mobs, killed without any meaning. MC know about stampede, yet he follow the route as normal human. he just goes along with everything. Not to thinking about the future. He just want to solve 1 problem (stampede) but have other problem unsolved ( who do this, why this happen, etc )
Everyone may think he crazy, but its good enough to make them remember. They are in forest where monster lurking around.]
And that is assuming anyone would believe him in the first place. Most likely than not, everyone would make fun of him. Worse if everyone thought he was crazy and pick on him, disturbing his concentration and even sabotaging him, that is assuming they don't leak what he said to outsiders, thus causing the attack to occur much earlier before he can be ready.
[Thats true if he just lazy-neet-hikimori. He doing his best with his father. Training, helping other, Hunting for food. Why they pick on him while they know his father is the strongest at village? sure the attack may be occur much earlier, but remember. He follow the flow event. As long he keep it moderate, no one will suspicion about what he did. instead he doing selfish shit.."looks like im not learned my lesson" and go cool "pose" imma protect this village. What he can do? got boost power from goddes? god? another plot wanna be overpower.]
If my best friend suddenly call me one day and say, "Hey, I came from the future. Get ready, we're going to get attacked by aliens in 5 years." I would be like, what drugs are you on?
[of course i told him, "are you kidding?" but your friend give you some "tip" to make you believe, there will an event where you are going to get attacked by alien in 5years later.] instead your friend doing his own with "imma overpower now, god bless me"
Could he have told his father and Tina? He could, but I can understand why he can't. If he told people and they make fun of him, his geas, his determination would've been set back and his actions would've been hindered repeatedly. Naysayers and teases can hurt more than sticks and stones can. He knows this will happen, and that is all that matters. He prepared everything and lives for this very moment.
[His determination would've been set back and his actions would've been hindered repeatedly? How? He training so hard for this day, that why he keep going with his dad hunting. But his actions still selfish. He telling us "i will protect this village with my own power" but the story " i cant save anyone, damn fate"]
Well, there's also the possibility that if he had told Tina, Tina would've wanted to fight with him. And we know how naive and annoying Tina can be. Tina is a glass cannon and he'd have to constantly watch behind him to ensure she doesn't get killed suddenly. Having to fight while having to protect her at the same time would've seriously hampered his effectiveness.
[Ofcourse if u are bland MainCharacter. Someone out there will follow you if they truly love you. Are you gonna tell her "Trust me.. i can do it" or you gonna tell her " Lets married after this?" or " I love you, that why believe in me, I will back to you after this WAR". Be serious, Tina will follow him even if that make her sacrifice herself. but If you told her, you love her. She will follow what you say. Because that the instinct we have, follow the one we love.]
Im not gonna tell this story bad or trash, but the MC action really selfish. he doing this to show off to us ..."imma protect someone with OVERPOWER borrow from GODDESS or GOD" bless me
