Valmiki Ramayana Ayodhya Kanda Sarga 75 Shloka 33

आर्यः esteemed one, यस्य whose, अनुमते with sanction, गतः was exiled, अकर्ता one who never helps, अकृतज्ञः च an ungrateful one, त्यक्तात्मा one who deserted his life, निरपत्रप: shameless one, लोके in this world, विद्विष्टो भवतु worthy to be hated.

May the one who counselled the exile of my esteemed brother be hated universally as one who never helps any one, who is ungrateful, shameless and as one who has committed the sin of suicide
