In what way exactly?
Every nation has done bad things in the past, sometimes a lot, sometimes small and that is still the case with many of them.
Even the youngest of nations have at least half a dozen bad points to them so to list them all could take a very long time.
With Spain the Spanish inquisition was one of the worst ones but naturally there were more than just that one.
More precision is needed with your question sorry.
Unemployment, drunken and disrespectful tourists, stupid locals (crecen cuervos types), arrogant foreign residents with no Spanish nor respect...
Uncontrolled Petty theft in big cities.
I prefer Spain to England having said all that. There is more freedom and fun.
