Sure, competition for resources would be harsh and violent. And hoarding isn't noble or particularly ethical.
But what is the alternative? I would not suddenly turn pacifist or fatalist and just wait to die. If there is some form of government or authority distributing food and water I'd try to help that entity. If not, I'd set out on my own with whoever I can trust within walking distance to find whatever can keep us alive.
And yeah, pretty much everyone else would be doing the same thing I expect.
