If you do not worship God, can you go to Paradise even if you did immense amount of good deeds?
What the Quran says:
Say: "Shall we tell you of those who lose most in respect of their deeds?
"Those whose efforts have been wasted in this life, while they thought that they were acquiring good by their works?"
They are those who deny the Signs of their Lord and the fact of their having to meet Him (in the Hereafter): vain will be their works, nor shall We, on the Day of Judgment, give them any weight.
That would clearly be something that is extremely wrong.
Now imagine how much more our Creator should mean to us - who gave us our life, our breath, our mothers, fathers... our ability to see, think, ... who created everything around us
If behaving that way with our mother is not okay, then surely behaving with our Creator is definitely not okay.
Allah gave us a brain, an intellect, a heart to know things with, we aren't like animals who only understand something when they see it. We must investigate the truth and search for evidences to why we are here... if we didn't do that and simply stuck to whatever our parents taught us, or whatever we had a whim to believe, then we are seriously failing ourselves, and doing an incredible wrong in ignoring Allah.
Now, a person can be kind and loving to their friends, to others, can be amazing in many other ways, but if he or she fails in their most primary relationship - with the One who created him or her, its a major failing that cannot be compensated by their other actions, no matter how beneficial those other secondary actions may be. It is thus that, no matter how good we are, no matter what good deeds we do, no matter how nice we are to our friends and family, if we do not worship Him, we are doing something terribly wrong.
