is this even legal??

my cousin (22m) has this gf (22f) and he wants kids really badly, but shes sorta reluctant abt having them,

then one day he told me shes pregnant and its bc he poked holes in the condoms, then when she said/did stuff like "morning sickness" "missing periods" etc. he'd reward her w her fav things,

i wanna tell some1 cus this feels kinda unethical.. she got pregnant even tho she tried everything in her to not have kids
