so yeah it's about that meat fruit, I'm little perplexed when im first read it, but after that im still focus in the storyline and forget about it, then i read the comments below and raus comments about imagine the tree, and this is how i imagine it, 
yeah its from resident evil 5 im watching that games playthrough rightnow, so from what i see so far this world is like after war or after apocalypse world that wipe off almost all humans and technology they have, maybe war against aliens since shelter is like a spaceship afterall, so after few hundred year or something there is still monster around, and maybe some of it becomes neutral and not aggressive, this meat fruit tree maybe one of it, try imagine in the beginning this tree actually eating human alive and make them as nutrition to grow meat fruits that keep seed in it to grow another tree, but after there is no human around they start to eat animal and then they become less aggressive and then after there is not much animal around because they become more smart to avoid this three, this tree then become more like normal tree that's grow with soil that grow meat fruit from what dna they collect before in this case it's maybe animal meat fruit and not human meat fruit. But we still don't know it yet, if this meat fruit actually have human dna or animals dna, but if we trust our boys nose in this vn then if this meat fruit is dosnt smell like our human luke meat, then it's pretty safe to say it's more like animal meat than human meat the end of my conclusion lol.
