Well, if your standard is that no one is a bad person until they are literally murdering people or selling war machines, then no, of course not.
But as a parent myself, I think it's fair to say that if you, as a multimillionaire, stoop to doing the bare legal minimum to support the child you created, who was at one point living in poverty because you failed to support her before, then yes: you are a bad person.
There are obviously many other ways in which Steve Jobs was a bad person! He kept obtaining temporary license plates because he wanted to park in handicapped spots without getting tickets. He orchestrated a salary-fixing cartel that artificially depressed wages for many thousands of engineers in Silicon Valley, all so that he and his other obscenely rich friends could get even richer. And he had his devices manufactured in China under horrendously exploitative conditions again, so that he and his shareholders could make an extra buck. (on top of the billions they already had)
But if your standard of being a "bad person" (not even evil!) is murder or complicity in it, then you could make a strong case that Steve Jobs was not a bad person, altogether.
Another example - in NYC a few years back, several people died when floodwaters entered their basement homes.
Mayor De Blasio: Climate change.
Local resident: you guys didn't clean out the drains, it's all clogged.
I'm not sure if I understand your logic. People who advocate to stop climate change (alarmists?) literally never use is as a convenient excuse "not to do anything." If you could provide an example I'd be happy to take that statement back.
Instead, the point is that, due to climate change, we're having more and more instances where something as trivial as a clogged drain can lead to people drowning in their basement apartments.
EDIT: On reflection, the so-called "climate change alarmists" who say you should "not do anything" are probably shills for big corporations, who want to save money on risk mitigation by saying there's no point because it's too late to mitigate the risks of climate change.
