Calling Jackson "evil" is going quite a bit too far.  Yes, he was a slave owner, supported the legality of slavery, but so did everyone in the south in the 1820's, 1830's.  And he was very harsh with the native Americans of the Southeast, sending them on the infamous "trail of tears" to Oklahoma.  But again, no one thought of Indian rights back in those days.

He did found the Democratic Party, and fought for the rights of common men over the rich and powerful.  Many do not know that he was called a Jackass by opponents while running for office, and ended up using the Donkey as a campaign logo.  That is how the Donkey became the symbol of the Democratic Party.

He was also a strong defender of the Union.  When South Carolina threatened secession in 1832 over tariff laws, he got Congress to authorize military force against the state.  But he then also got a compromise tariff bill past by the Congress, to help avoid the harm the old tariffs were doing to South Carolina.
