Who is the kindest Sonic characters?

I'm curious, among the diverse cast of Sonic the Hedgehog characters, who do you think embodies the most kindness? Is it Tails, always there to lend a helping hand and with a heart of gold? Or perhaps it's Amy Rose, despite her initial outward appearance, who shows a deep caring and affection for her friends? Or maybe it's an understated character like Cream the Rabbit, whose gentle nature and love for her Chao companions speaks volumes. I'm eager to hear your thoughts on who you believe is the kindest Sonic character.
