The problem here? 2014!Thanos makes it very clear that he is doing this both out of spite and because the people in the current timeline didn't sing his praises for his sacrifice. There's a fine line with destroying the universe and recreating it because you find it as "good" and destroy everything because you were offended that others were critical of your work.
