- live in an impenetrable fortress from which they launch raids on the innocent, never suffering the consequences of the evil they commit
- ruled by the most cruel and decadent amongst them, but don’t do anything about it because they dream of being on top of the horrific pyramid of torture and pain one day
- innately cruel and horrific society where seeing others suffer is the only source of pleasure
- slavers
- violence is the only language they understand
- sense of racial superiority
- entire sectors of society dedicated to coming up with evil and sadistic weaponry with which to commit war crimes
- hopelessly addicted to drugs of all kinds
- complete lack of compassion
- piracy
- love to torture


Even if that’s the case the fault would be with the creators. The tyranids couldn’t be held responsible for being created the way they are. But yes, they are bad for anyone who’s not a tyranid obviously lol
True, I’m just saying they’re not necessarily a ‘force of nature’(in academic terms, rather than as a simile or metaphor i.e. ‘like a force of nature’), not that being so or not affects the maliciousness or lack thereof of their motivations
