Evil sims can be very fun to play, as long as they're not destroying every relationship they have! The two I've played in my TJ game both had the trait counter-balanced with the family-oriented trait and the friendly traits, respectively----but poor Heath, the only boy in the 1st gen really got the short end of the stick, being born an evil, slob, getting loser as a child, then his one positive trait, family-oriented at teen, followed by commitment issues for his YA trait! What a combo that was, but he turned his life around and focused on his family.
Luckily, Ida's gotten better spins on the trait wheel and with Kiera out of the running for heir, it's now down to only two, Ida and Bennie, the evil duo, or Josie and Ronny!
And what a beautiful kitty to add to the family----welcome Katara!
