Time travel is something I personally avoid because unless it's using multiverse theory where it's merely an alternate dimension timeline it has paradoxes by default. Time travel by premise has no set limitations but I see a potential issue with avthing you just said: your idea forbthrm to only be able to transport to the future makes it impossible for them to go back to even the present. As for keeping the scientist dead you could technically have him brought but needing to sacrifice themselves to help shortly after and the time machine to malfunction or be destroyed, one way is if possible having the ultimate villain enter it and the scientists cause the time machine to jump to an alternate dimension outside of time and self destruct. This could ve a way to either kill both or leave the ultimate villain in a fate worse where he's permanently trapped in a limbo where no one could leave or get help. Just a thought to try to help.
